GrapheneOS is such a staple for me now. Been waiting for it to be released for the Pixel 8 since I got the phone at launch... it doesn't have the annoying search bar or the unmovable widget telling you the weather... Regardless of the security and privacy it offers... And its just pretty.
ADP, Chase, Amex, Citi, and my small credit unions apps all work. I think I had to turn that compatibility option on for Amex to get it to launch but no issues other than that.
Unfortunately it's just this specific app that (they say) doesn't work on non-mainstream android os's. It specifically generated 8 character codes and you use a URL instead of a string of characters to register it. According to the comments it doesn't work on jailbroken devices either since it scans your other apps and won't work if it finds something it didn't like. If it was just a general 2fa app then I'd just switch to a different one and have switched to grapheneos
My gripe with the weather isn't that it's there, it's that it disappears sometimes for days and it's too small to click on it. I tried to fix this by adding a separate weather widget, but that means I now have 2 weathers on my home screen and I can't get rid of the one that doesn't work :/
If it's any consolation, installing GrapheneOS through the web installer was surprisingly straightforward and easy. I haven't installed Linux since that seems difficult for me, but GrapheneOS was a breeze.
Its insanely easy, the hardest part is putting the phone into fastboot and installing the USB drivers on windows. Then its just click buttons on the WebUI and pressing the buttons you're told to. The whole process takes about 10 mins.
Check out some YouTube videos on it, its the same process for any pixel (its also the same process for CalyxOS if you want microG)
