I hate, hate, hate, that I can't turn off the "At a glance" top section as well as the "Google search" bottom section in my Pixel home screen.
They got rid of the Google Assistant microphone icon that I could tap and say stuff like "remind me to buy milk in 2 hours," and replaced it with a similar icon that does voice search. Yuk (and no, shaking, squeezing, gestures or activating the always on 'hey google' prompt are not worthy replacements.)
Here is a list of most banking apps and whether they work or not. I've been using GrapheneOS for a while and haven't encountered major problems. Only thing I wish I knew beforehand is that multi-user profiles are more cumbersome than what most people say.
Huh, I actually had to look at the At a Glance but to see what you were talking about. I've just taken it as a given that I can't use the top 1/3 of the screen or the bottom strip.
