There is no unread message on the mobile phone, but there is still an unread message on the message. How to delete it?

I have encountered the same problem. The status bar icon displays 1 unread items, but the button on the right does not display unread new information. I searched up and down several times for information, but I couldn't find unread information. I tried to update the system, restart the computer, quit Messages, and log in to iMessage again, all to no avail.

Problem and Solution: There are unsuccessful messages, but it is difficult to find out which message was not sent. Only by clearing the message can it be solved. Open Messages preferences, change "Keep Messages"-"Permanent" to "30 days", exit Messages and open it again, and messages over 30 days will be cleared, and basically unread messages will disappear.
