A.7 Apple Volume Purchase Program

Purchased license count is not updated, if sync to retrieve latest VPP apps is initiated immediately after purchasing an app

Explanation: If a sync between the ZENworks Server and the Apple Server is initiated immediately after purchasing an app using the Apple VPP account credentials, then the purchased license count might not be updated with these latest app purchases. Subsequently, bundle assignments might fail.
Action: Ensure that you verify the purchased license count for that specific app in the Apple VPP License Summary page, before assigning that app to a device or a user. Wait for the next sync or re-initiate the sync to update the purchased license count.

While uploading or renewing a VPP token, an appropriate error message displayed and the subscription renders as unusable.

Source: ZENworks Mobile Management.
Explanation: If the existing token or the renewed token is managed by another MDM solution, then an appropriate message is displayed and the subscription renders as unusable.
Action: Delete this subscription and create a new subscription. To continue using the same token, you need to claim management of the token.
