Phantom badge in Messages
I'm running macOS Monterey 12.0.1. Ever since the update, my messages have a phantom badge. I've tried some of the fixes that others suggested in 2018, but I suspect this is a newer problem. I've tried closing Messages and restarting the computer. I've tried going into terminal and typing killall Dock. Neither works.
Any ideas to get rid of the badge short of turning off notifications?
