iMessage badge count incorrect on Mac mini/Ventura after removing messages on iPhone
Received three iMessages in a single thread; iMessage badge count went correctly up from zero to tree on both my Mac mini and my iPhone. Deleted the thread on my iPhone; messages were correctly removed from my Mac mini too (I have iCloud messages enabled on both devices). Badge count correctly disappeared on the iPhone, but stayed at three on the Mac mini. Quiting iMessages on both devices and opening them did not resolve the issue. Selecting "View -> Unread Messages" in iMessage on the Mac mini correctly showed no messages, but the badge count stays at three nevertheless.
Mac mini on Venture 13.0, iPhone Xs on iOS 16.0.
