Bellooch , via OnePlus 8T , May 25, 2022 : After the update to 12 I am not getting notifications of text messages (visual, audible, haptic). I've tried everything but resetting the phone. Which, I just don't want to do. It's my understanding there's a new update that fixes this but I haven't seen it or found it. Haven't found any other viable fixes.
