AAPP-2639: iOS devices stop communicating with MDM server if scheduleOSUpdate command is used when devices are on LTE

Identifier

AAPP-2639

Symptoms

When a scheduleOSUpdate command is issued to an iOS device on LTE, the device stops communicating with the MDM server after processing that command. All commands issued moving forward remain in the queue indefinitely. Communication is restored as soon as the device is put on Wi-Fi.

The following three ways can be used to issue the scheduleOSUpdate command from AirWatch:

1. Query or manually force the update from Device Details

2. Query or manually force the update from Device List View

3. Configure a compliance policy with a force OS Updates escalation
