Apple ID or password is incorrect when restoring purchases from another Apple ID
Oddly enough, I was able to resolve this by deleting the application in the Finder (open Finder, Go &gt; Applications menu item, select the App in question, drag to trash) and then allowing the App Store to re-download the application while signed in to my personal Apple ID. So it appears that somehow the Apple ID you are signed in to when you download software is stored or recorded with the actual application package directory inside /Applications, at least under 10.15.
