email messages disappearing
Just since updating to OS 11.2.1, I have an issue with macmail. After I read a message, the message disappears. The mailbox is visable but any mail I've read is no longer showing in the box. I haven't marked it as junk or delete. If I do a search for it, I can find it but it still doesn't show up in the mailbox.
Any thoughts?
