Very good question. The Piskei Tshuvos 5:492 brings down that scrupulous individuals are accustomed to eat matzah on peasach sheni. In footnote 9, he brings down that in the siddur Yaavetz (Rav Yaakov Emden) that it was revealed to him from the heavens that the kedusha of pesach and matzah lasts until pesach sheni because when they went out from Egypt they ...

R' Eizik Vitebsker writes (look in Os 26) that the origin of this Chumra was from the Mezritcher Maggid.
R' Shneur Zalman of Liadi explains that since some opinions say that flour which was baked (without being kneaded first) can still become chometz after contacting water as it may not have been baked well.
He writes that (at least in his time) one could ...

Rakusen's of England makes cracker-sized machine "tea matzas", and they're round! (Mind you, you'd have to eat a few of those "crackers" to have a complete serving of matza for the mitzva.) The only ingredients are flour and water, so they truly are matzas. I've occasionally seen them in American supermarkets.
With the early machines in the late 1800s, they'...

An original source of this custom is the Sheyare Knesses HaGedola Siman 471:3 where he writes that the custom in Kushta (Istanbul) is to avoid eating matza as of Rosh Chodesh Nissan.

This does not include the time in the oven, but the notion that the entire process until the dough goes into the oven must be completed within 18 minutes is based on actual opinions on the books.
I found the sources cited below and got help in understanding and contextualizing them via the following contemporary English digests:
R' Eliezer Melamed, Peninei ...

The roots of this minhag actually lie in the Gemara itself. In Pesachim 40b, there is a discussion which says explicitly that Rav Papi allowed servants in the beit Reish Galuta to thicken a tavshil with "chasisi." The Rif says this is matzah meal; Tosafot say it is lentil flour, and Rashi says it is dried flour. Rava says we need to be concerned in a place ...

If such matzos are rare or nonexistent, it's because they don't fit as well in a box and thus require either
a round box, which costs more to make and assemble, or
both
more box space per matza, taking up valuable room in shipping etc., and
empty space in each box, increasing the likelihood of breaking matzos.
Source (so to speak): conjecture.

The Gemara in Pesachim 46a (brought in the Rambam Laws of Chametz 5:13 and the Shulchan Aruch OC 459:2) says that if one leaves dough for the length of time that it takes to walk 1 "mil" (a Talmudic unit of distance) then it becomes Chametz. Opinions regarding the time it takes to walk a mil vary from 18-24 minutes, and here we are strict to take the shorter ...

Matzah made with other liquids besides (instead of) water are called "matzah ashira" enriched matzahs. While some object to them because they undercut the "lechem oni" bread of affliction that water/flour matzot represent, there are other concerns regarding whether they create an environment for fermentation.
Here is one treatment of the argument with the ...

From the Star-K:
Matzos left over from previous years that were stored in places free of chometz may be used. TIP: If your oven has been kashered for Pesach, simply put them in the oven for a few minutes so the matzos will regain their crispness.

In שו"ת מהרי"א סי' קנ"ז (seen here and continued here), it speaks about the shape of matzos being specifically round. This was written during the period of controversy regarding machine matzos.
The word עוגה (as in עוגות מצות) means round.
At first glance the word "עוגות" is superfluous; why do we need to know what shape they made their matzos? And ...

The Mishna in Pesachim 2:5 reads as follows:
אלו דברים שאדם יוצא בהן ידי חובתו בפסח: בחיטים, בשעורים, בכוסמין ובשיפון ובשיבולת שועל
These are the things with which a person may discharge his obligation on Pesach: wheat, barley, spelt, rye and oats.
[Note that these are the commonly accepted translations of the five grains. As mentioned by Dan F in ...

Extra watched: to make sure that no water touches it (except while it's being kneaded), because water is needed to start the fermentation process, which would make it chametz.
The soul is connected to G-d, like a limb of the body is connected to the heart (for its blood supply) and the brain (for its functionality). "Cut off" means just that - that ...

Per the Nitei Gavriel Pesach Volume 3 Chapter 19:9 one may prepare them on Sheviyi Shel Pesach so long they made an Eruv Tavshilin.

The Mishna Berura (471:12) brings that the custom is not to eat Matzah from Rosh Chodesh. One of the sources he brings in the Shaar HaTzion is the Chok Yaakov. The relevant Chok Yaakov is here.
There (471:7), he quotes Sharei Knesset Hagedola brought in this answer. Interestingly, he quotes it as saying from "Rosh Hashanah", which I'm assuming in this case ...

The Mishna Berura (OC 471 sk 10) points out that one may eat Matza Ashira (eg. Egg Matza) on Erev Pesach because one cannot fulfill his obligation to eat matza on seder night with it. Seemingly the only things that are forbidden to eat are those with which one can fulfill his obligation to eat matza.
Products using matza meal which are cooked in liquid ...

According to the Bedatz of Crown Heights,
It is told that the [Lubavitcher] Rebbe's household was accustomed to to eat gebrochts in the form of kneidlach on the final day of Pesach - regardless of whether the final day coincided with Shabbos. Naturally such foods can be prepared only if one had made an Eiruv Tavshilin.

The 18 minute mark is almost certainly a mistake. The source of this time limit is from Pesaḥim 46a:
Mishna: [Regarding] ‘deaf’ dough, if there is [a dough] similar to it
which has become leaven, it is forbidden. Gemara: What if there is
no [dough] similar to it?―Said R. Abbahu in the name of R. Shimon b. Lakish: [The period for dough to become ...

Rav Herschel Schachter has written a Teshuvah that Ashkenazim may eat soft Matzah. See here* for a discussion of his Teshuvah and some follow-up questions and answers about it.
*Be advised that this is taken from a commercial site selling a product under the umbrella of "approved by Rav Schachter". It is, however, a real Teshuvah, and the discussion that ...

(To fulfill the Mitzva of eating Matza at the Seder the Matza must be made with proper grains (Mishna Pesachim 2:5) not Kitniyot. The foods being discusses here are being called "Matza" more as a pseudonym because of the similarity of the baking process involved.)
Chayei Adam 127:1 says explicitly that rice Matza is allowed.
Shulchan Arukh HaRav 453:5 says ...

Yes it is permissible, but you have to be extra careful how you handle stray pieces of dough or leftovers in the kneading trough which might become Chametz (see ShA OC 459:4 and 460:3 for details).

You cannot begin to recite Kiddush, drink 4 cups and eat matsa and maror before the night (exit of the stars, later than sunset). The time the Jews left Egypt was at night. And the korban Pesach and matsot were eaten at night. Further eating of pesach dorot was established by Tora as a night mitsva.

In Holland, round matzot were made before the Shoa; the only matze available is made by the matza factory de Haan, Valkenburgerstraat, Amsterdam and Hollandia Matza in Enschede.
After the Shoa until today, you can buy round machine matzot from Hollandia matzes.

The Lubavitcher Rebbe (Igress Kodesh vol. 2 pg. 353) quotes the Darkei Chaim VeShalom of Munkatch, that although the eating of the Korban Pesach took place on the night of the 15th of Iyar, since they would offer it on the 14th we customarily eat Matzah then - as the beginning is considered the main thing. (However, the Munkatcher would be careful to eat ...

R Israel Isserlein was asked this question. Here is his response (Terumat HaDeshen #125):
קטן בערב פסח, שרי להאכילו מצות או לאו?
תשובה: ייראה, דאם לא הגיע הקטן לכלל דעת כל כך שיודע ומבין מה שמספרים לו מניסים ונפלאות ביציאת מצרים, שרי להאכילו. ואף על פי דאסרו חכמים לגדול אכילת מצה בערב פסח מזמן איסור חמץ ואילך, וקיימא לן דלא ספינן בידיים איסור ...

As per Otzar Minhagei Chabad, which in turn quotes from R' Leibel Groner (the Lubavitcher Rebbe's personal secretary):
The context here is discussing the fact that while throughout pesach Chabad does not eat gebrochts (matza shruyah), on the eighth and last day of Pesach, they make a point to davka eat it.
Quick translation:
When the last day of Pesach ...

It's interesting that another answer mentions the Alter Rebbe's answer as the origin, but fails to clearly explain the history of how/why this minhag suddenly started.
Why isn't this minhag / worry mentioned by any of the poskim ??

Kefula means "doubled over." We have the same root word used in the morning bracha "zokef kefufim" (He straightens those who are bent over), or in upcoming Daf Yomi, "tenai kaful" (a legal stipulation where both possibilities are spelled out, if x then y, but if not x then z).
Then there's nefucha (swelled matzah), typically a bubble, similar in appearance ...
