Apple Mail - Can Not Find One Single Unread Mail
Hi,
Apple Mail - Catalina - can not find one unread mail. I have several smart folders on left sidebar. and some show 1 unread mail. When I choose filter unread (top right) on any of these folders they are empty.
I want to find this single unread mail and make it read but can not find it. How can I clear out this single email unread count?
