Mail freeze in Big Sur
My new M1 MacMini has suffered two mail freezes in Big Sur, don't know if an OS bug or a computer bug, but when it happens the spinning ball appears, can't send or receive mail, cannot open mail prefs and can't even quit mail because the quit mail link goes gray. Only way is to force quit with the escape key and the only way to get mail to work again is to restart the computer. Has anyone else had the same experience?
Mac mini, macOS 11.2
