So I've used the administrator bypass to leave the lockdown screen on a Samsung Galaxy TabActive 2, but now I can't seem to find a way to get it back into lockdown mode. I've looked in the mobicontrol app on the device, tried sending "lock" on the web console, and tried both a soft reset and a power off. Each time it just opens back up to the device unlocked in administrator mode.

I'm sure its something really easy, and I'm just missing it. Can someone help me out here?
