Updating Apps: Based on the schedule selected while creating the Apple VPP Subscription, ZENworks syncs with Apple to retrieve the latest apps. However, irrespective of the schedule selected, ZENworks automatically syncs with Apple on a daily basis to retrieve the latest apps. Bundles are not created for any newly purchased apps during this sync.
You can also initiate this sync immediately by performing either of the following:
Click Run Now by navigating to Subscribe and Share > <Select a Subscription> > Quick Tasks > Run Now or by navigating to the Summary page of the Apple VPP Subscription. This option also creates bundles for any newly purchased apps. For details, see Viewing or Editing Apple VPP Subscription.
Click on the Apple VPP License Summary page. For details, see Viewing Apps Catalog.
Updating Distributed Licenses: If an app license is assigned to a device or a user, then the license consumed and installed count is updated when the associated devices syncs with the ZENworks Server. Subsequently, the app is installed on the device.
Revoking Licenses: Unused app licenses are revoked when the device syncs with the ZENworks Server. To revoke licenses from devices that cannot sync with the ZENworks Server, click on the Apple VPP License Summary page. This option can be used to revoke licenses in the following scenarios:
Mobile device management on the device is disabled.
The device is in a Retired or Wipe Pending state. In case of a device assignment, all apps assigned to the device are revoked. In case of a user assignment, if the device is the last device associated with the user, then the app licenses are revoked from the user.
Bundle assignment is removed.
User does not exist anymore.
Alternatively, ZENworks periodically (every two hours) revokes unused licenses from devices that cannot sync with the ZENworks Server. However, if you do not want to wait for the device to sync or for the periodic schedule to revoke licenses, then clicking helps in revoking licenses instantaneously.
If any of these tasks fail, then the relevant error messages are displayed when you visit the Volume Purchase Program License Summary page.
