Menu screens from different accounts sometimes overlap
Periodically, when viewing the inbox of any of my accounts, the menu selection (hamburger) button is replaced by a back arrow. If pressed, I have the option to switch between accounts, as I would normally, but when the new account inbox is presented, it is superimposed on the original account inbox, leading to an unreadable inbox. The only way to clear the error is to "Force Stop" the app and restart it.
