I had an issue with one banking app, but that might be because I had the second degoogled user going at that time as I tried to see how some of my apps worked that didn’t have any data on if they work or not.

I also had issues with a game called Root, Play store suddenly said it was not compatible but I installed via Aurora while spoifing a different phone and it continues to work fine.

There were some minor hiccups on some apps that were fixed by disabling some exploit protections built into Graphene (a simple Exploit protection compatibility mode toggle in the app settings).

Overall I’m really happy and if I wasn’t concerned about Google further closing down the Android ecosystem, I wouldn’t be considering switching. I never had a situation where I thought I’d be better off on stock Android
