App connects fine, but once logged in, the menu can't be accessed due to lack of safe areas. The top of the app gets behind the status bar of the phone, making it impossible to enter the menu. The email list does not scroll, navigation does using the phone gestures takes the user out of the app, and since the top bar is not accessible navigation in general does not work... It seems it was tested only on the web, the android app is unusable.

Good, but technical issues on Pixel 9. The menu bar is so far up the screen that it overlaps with my time/battery/wifi/signal status bar on my phone. This means I can't press any buttons to close an email draft or select options on the dashboard. Leaving a good review because it's still a good service on my desktop, but the android app needs work.
