Issues after One UI 7.0 update

[Car_Tech_Guy]

I've had so many issues since this update, battery drain is epic, 10% drain in 20 minutes, also icons/fonts smaller and notifications not showing for WhatsApp.

And earlier this evening, apps kept opening then just crashing and shutting, please fix this or I may consider consumer rights action due to unfit for purpose now. 

And........Thats to start with, I think Samsung have really dropped the ball on this one, Samsung if you're listening, please rollback.

I have the same issue from the day i upgraded to new version. Apps are crashing too frequently.  Even making or recieving calls have became hectic as the ui froze too frequently.  Tried clearing cache didnt work. Even all the apps have no recent updates available.
