Apple notification services

Endpoint Manager uses the Apple Push Notification Service (APNs) to communicate with Apple devices, which requires you to have an APNs certificate. Once you have obtained an APNs certificate, communication will be enabled, and you will be able to enroll and manage Apple devices.

APNs certificates expire after a year. You must replace the certificate before it expires, or else you will be required to re-enroll devices.
