Which version and phone are you on ? I’m on “t” version on a Oneplus 7 et I have none of these issues.
I first installed the “s” version and got annoying bugs, then switched to the “t” one and everything was OK. I now all the version aren’t available on every devices, I hope you can switch on a more stable one.
That’s great !
R and T should have a different android base, so, It would be safer to wipe everything while upgrading.
