In this context GApps stands in for GMS (Google Mobile Services). You can use any GApps addon package you prefer. We suggest these.Thank you so much! I feel like a lot of the disparate information is beginning to come together in my mind. I have now the phone back to stock Andorid 11, and I will try to follow the LineageOS wiki precisely to try flashing Lineage again this weekend.
I read through this thread from the beginning and I am left with one thing I want to clarify. I am using Google Fi with an eSIM, and I see that the first post says gApps is required for that support: what I want to clarify is if that mean OFFICIAL gApps only (because it needs to identify you individually), or would something like microG or Open gApps work for an eSIM on this phone?
MicroG may work, although it's not supported by LineageOS.
