APP Store not working
i just updated to Catalina and i can't get access to the APP Store--the app store screen is blank and the pin wheel just keeps going (I've tried to power it on/off). any suggestions?

Since you just upgraded to Catalina, you might need to reauthorize your Mac. See the "How to authorize a Mac or PC" section in:
