After a (generally) successful migration from an old MBP (2014, Big Sur) to a new M2 MBA, I have several unread messages indicated by the notification badge in the dock on the iMessage icon.
I've tried rebooting, logging out and back in, killall Dock
, and even clicking on every single thread in the messages app, but nothing works.
How do I get rid of the phantom messages?
FWIW I don't have this issue on my phone connected to the same account.
