I don’t intend to go to shul on the 1st day Rosh Hashanah as it is Shabbos and there will not be Shofar.
As for the 2nd day I am debating whether I could go to shul, masked, just for the 1st 30 shofar blasts, and then come home or stay for the whole of Mussaf and all the shofar blowing.
I will have to ask a Rov as I am vulnerable and still Shielding.
Also does anyone know whether Hataros Nedarim has to be done with 3 people together or can it be done over the phone or by Beth din document?
