I have much the same issue with some Samsung apps that won't shut up and go away on my Android 11 powered A51 (3 months old, already had to replace a defective screen - so much for the former days of Samsung "quality".)
I also have a Google weather notification that I can't shut up.
My phone is a tool. Unless it is a text from someone I know or a phone call or an alarm that *I* set, I expect it to be absolutely SILENT unless *I* am ready to interact with it.
If I wanted a Tamagochi, I'd have bought one on eBay.
