I daven Nusach Ashkenaz saying “LeDovid HaShem Ori” at Shacharis and Maariv.
Q1 If I daven Mincha with a Minyan which says “LeDovid HaShem Ori” at Mincha, should I say it with them? (I assume yes, in order not to separate myself from the Tzibbur).
Q2 If I then daven Maariv in the same Minyan (which now does not say “LeDovid HaShem Ori”), am I obliged to say it? I realise that this is a case for CYLOR and will do iy”H.
