An 'invalid_access_token' error means that the access token used to make the API call isn't valid, e.g., it wasn't a valid access token, was revoked by the app or user, the app folder (if using that permission) was deleted, or the user account was deleted, etc.
Having the user re-authorize the app if they want to keep using it is the right solution. That would give a new access token to the app. Can you double check that the app is using the new access token, and isn't accidentally holding on to the old one, and isn't somehow changing the access token itself?
If that doesn't seem to be the problem, please open a ticket with the relevant app name, account ID, and steps to reproduce the problem so we can look into it:
