I ran into this over a week ago, attempting to launch Sound Studio, which had been running reliably for years with no issues. Asked to sign into the App Store, which promptly rejected my Sign in. manifested on both my older Classic Mac Pro (5,1) workstations running Mac OS High Sierra and Mojave.  After two fruitless episodes with Apple Support, I threw up my hands and bought a new license from Felt Tip. I had a project to finish. I downloaded the app directly from their web site. I reasonably suspected Apple, as I could sign into my Apple Id account, iCloud, iTunes, the Music Store...

Yesterday, I found sign-in access had been restored on both machines, through no effort on My part. Apparently Apple quietly tweaked or fixed the App Store backstage.

Apple did this. Reminder: Upcoming Changes to the App Store Receipt Signing Intermediate Certificate. They informed developers, but not a word to customers. It seems that Apple Support either did not know, or was not permitted to tell us.

All Apple support needed to say would have been – "Sit tight. We’re aware of the issue and are working on it.” – Just THAT. Grrr. Arrgh. Cost me an un-needed software license, three working days and half a weekend putzing around trying various technical fixes to no avail, including re-installing MacOS High Sierra on Workstation #2. Pain. In. The. Arse....  As least I won’t have to buy a Mac $tudio.... This Week.
