After many issues with the beta, I had to do a factory data wipe/reset. Once that was done I have had zero issues with app downloads, app updates, app crashes , battery issues , watch connectivity issues, display issues, etc. Even the shop samsung account issue is no longer an issue. With that being said, I actually am enjoying Android 12 now. Let me know what issues you're having and I will try to replicate it and get back to you.
