I've tried looking through settings to see if there's a way I can monochrome things.

Either it's not there or I'm a dumbass and completely blind. 🤣 I'll get used to it eventually. It's just annoying. I put a lot of effort into making all of my icons monochrome on my home screen. So it's annoying to see my notifications All colorful.

Massive, massive first world issue though. 😅
