I might have found another small issue but not sure if it’s worth opening an issue for it.
If you install the app for the very first time you get greeted with the account adding screen. If you don’t want to add the account right away and exit the app this is not possible as pressing the back button (being hardware or software button) keeps displaying the add accounts page again instead of exiting the app. So in this case you have no way to exit the application. You can simulate this by deleting all your accounts in the app.
I only noticed it because i factory resetted my phone during the weekend
