I changed my Adobe ID for my paid subscription account 12 hours ago to a different email address. I then logged out from Creative Cloud in Windows, on my Mac, and on my Android Tablet and then logged back in with the new email address and now Creative Cloud on my Mac and Windows show the new Adobe ID email address after signing-in.
However, on my Android tablet...
Things I have tried:
The two Android apps always show the wrong Adobe ID email address after signing in with the proper new Adobe ID email address.
