Description
Devices must have a network connection in order to receive management commands from Jamf School. If an iPhone or iPad in Single App Mode loses Wi-Fi connection it can become "stuck" in Single App Mode since it cannot receive the command from Jamf School to remove the Single App Mode profile.
Connecting to a Network
In order to leave Single App Mode, follow these steps to restore network connectivity.
Attempt to Connect to a Known Wi-Fi Network.
Confirm the device is within range of a previously connected Wi-Fi network. If the device was connected to a known network previously, it may automatically reconnect.
Use an Ethernet Connection.
Connect the device to a network via Ethernet using a USB-C or Lightning Ethernet adapter. This option provides a stable connection that can allow the device to receive the command to exit Single App Mode.
Restart the Device in Recovery Mode.
Put the device into Recovery Mode (following Section 2 here) and choose the Restart option in Apple Configurator (ensure the device is connected to a network during this process).
Wipe and Re-enroll the Device
If none of the options above work and the device still won't connect to a network, the device needs to be erased in order re-enroll and communicate with Jamf School again.
