Assignment of applications to desktop not working as expected
I have just migrated to a Mac Studio running Monterey from an iMac 27" running Catalina. On both I is/was a dual monitor setup.
I use spaces (3), the Main Display is used for work and the Extended Display is used for internet & mail. Applications on the Extended Display show on every space, whilst apps on the Main Display are assigned to 1 space.
Since I've moved to the new setup, the assignment of applications to specific displays seems a bit glitchy. For example, Mail is assigned to Desktop on Display 2, but when I select this the None option is also ticked.
If I then select All Desktops, only that single option is selected.
If I then select Desktop on Display 2, then None is once again also selected. Because of this after a restart or even when waking from sleep (if I leave the mac on overnight) then the Mail app is shown on Display 1.
