Problems deleting email messages from Inbox on Monterey
Since the upgrade to Monterey, Apple Mail has been acting strangely. When I'm reading messages in my Inbox, and click the ""Delete" menu bar icon, instead of the message disappearing into a trash folder, it just stays on screen in the Inbox with the blue unread dot, with the "Delete" icon changed to a grayed-out "Undelete." The only solution for me has been to Quit Mail and restart it. Then it's finally gone. Any suggestions?
