Single app mode will not let me power off the device
Single app mode will not let me power off the device.
Solution: Press and hold the HOME/Power buttons for at least 8-10 seconds. You will see the iPad shutdown, continue to hold both buttons. After about 4-5 seconds the unit will start powering up again displaying the Apple logo, continue to hold both buttons and after few seconds the unit will finally shut down and stay off.
Hope this helps. (I got the info for my MDM vendor)
