I upgraded from Catalina to Monerey 12.0.1 (skipping 12.0). A few days later I noticed that Norton 360 was not running. I tried to launch it, but it hung with "Pending" displayed. I uninstalled Norton 360, logged into Norton and downloaded the latest Norton 360. I installed it, but after reboot it's not listed in the Applications folder. I repeated the install/reboot, but got the same result.
I've asked your thread be moved to the Mac forum board for better exposure to Mac users.
