Oneplus 8T and Android 12 issues

I also recently updated on 8T and I absolutely hate it. Firstly, I can't click on pictures on FB - it crashes the entire app. Even though I have always on display turned off, the fingerprint symbol constantly pops up when screen is locked so I accidentally hit it all the time. The way the notifications now only show on the lock screen when they're brand new is ridiculous. If I leave something in my notifications because I want to be reminded to check it later, it doesn't show on the lock screen after I've unlocked the phone, regardless of clicking the notification or not. With the notification bar there's issues too, if I get 3 texts from 3 people, it only shows the most recent message icon - not all of them which is also ridiculous. Not to mention the update made the home screen, lock screen, apps, chat bubbles, and literally everything look absolutely horrible. I hate this update.
