A problem was found with the latest version iOS 9.2, linked to the evolution of Apple APIs introduced in this latest version , which impacts devices already enregistered on the MDM platforms.

Impacts on iOS 9.2 devices:


Internal AirWatch and Apple teams are working closely to find a solution as soon as possible after.


We recommend not to proceed with the update of iOS devices to iOS 9.2 until the issue has been resolved. Some customers indicate random and intermittent functioning.  By repeatedly reregistering the device you can unlock and temporarily solve the problem, but this is without any guarantee
