macOS 10.14.6 Mojave - can't update mac apps from the Apple Mac Store

I see last October someone had this issue and an OS update seemed to help. Even if I delete and app and try to reload it-- I can't!

I took the latest updated versions of the apps (WhatsApp for Mac was one) from my MacBook Pro running macOS 11.2.1 Big Sur and copied them to my Mac Mini running macOS 10.14.6 Mojave. The apps ran fine but the Apple Mac Store still says they need to be updated and still cannot update them.

A bit of a confused mess.

If anyone has suggestions or has found a way to fix this please let me know. Need Mojave for this Mac Mini as I have a few 32 bit apps that I still need for now.

THANKS!

Best regards,

I can confirm that Apple Engineering applied a fix yesterday. I was able to confirm myself today and then asked for root cause analysis that I could share here.

From Apple:

As it has been explained to me with the recent security update for Mojave when the App Store launches, it asks appstoreagent for adoption eligibility. The issue seemed to stem from a wrong file type that was being provided by the process which caused a hang. After that was readjusted by our engineering team to be a compatible file type the issue seems to now be resolved.

If anyone has a reoccurrence of the issue, they can reference Ticket #: 214029
