After being unable to find any link for the S21 Beta 1--> Beta 2 OTA, I decided to revert to Android 11 via Smart Switch (PC version). Shortly after that was finished, I opened the Samsung Members App and was immediately greeted with an invitation to join the beta program. I never had the option before, and I have a factory unlocked U1 model bought from Google Fi.
Since users will likely have to downgrade anyway to receive future official builds, you might as well try. Smart Switch for PC was something I didn't even know existed until now, and it was much simpler and faster than ODIN flashing (I assume safer also).
Beta 2 is much better than Beta 1 in my experience. On Beta 1, callers could not hear my voice about 75% of the time for no apparent reason. Mic worked just fine elsewhere, but it was an extremely frustrating issue that I couldn't even report bc I wasn't officially in the program yet.
TLDR: Smart Switch for PC, downgrade to last stable, check members app after.
