Still on Catalina 10.15.7 MACBOOK PRO. Not planning to upgrade though.
Photoshop is acting strange in that I switch to the Move Tool but the tool only remains on the Brush - whether or not I was using the Brush, Cannot select a different tool no matter how many times I click. This is repeatable. Happened last night and now, after about an hour it is doing it again. Only remedy is to exit and restart.
