App Store subscription not recognized on one computer, but remains working on another Mac logged in using the same AppleID
I have a MacOS app downloaded from the Apple App Store with an active annual subscription running on a desktop Mac. After the subscription automatically renewed the services I have been subscribing to stopped working in the app exactly one month after the annual renewal date restarted. It is as though the app does not recognize the annual subscription and thinks it is a monthly sub. Now all I get is prompts from the application to subscribe when I try to use it.
To address the issue, I tried deleting the app and reinstalling it. However, I got the same results.
On the advice of the application developer I tried deleting the app, logging out of my Apple ID account, restarting my computer, logging back into the app store under the same AppleID and reinstalling the app, but that didn’t help. I then tried repurchasing my app subscription when prompted and receive the error message "Transaction Failed”. When I go to manage my app store subscriptions I see that the subscription is still active and renews in 11 months.
When I log into a different Mac (my MacBook) using the same AppleID, making sure that the application in question is current, the subscription appears to be active, the application works fine and I have access to all of the features I paid for.
Why is the subscription working on one of my computers and not the other? The application seems to launch fine and is compatible on both systems. I can use the free features, but the subscription appears to be inactive on my primary computer.
All I can think is that there might be some residual files that are keeping the app from recognizing it is on an annual subscription. Is there something I can do to wipe the entire app off of my computer including any ancillary files before I try reinstalling it again?
