In doing testing on iOS 14.6 with console commands, we noticed that once a DEP device has been put in Lost Mode, that mode can't be disabled. Either get a Failed or Pending in the console that never goes away. The only way to get out of the mode was to initiate a wipe command from the console which worked. After doing the wipe and enrolling back into Intune, the Lost Mode was successfully enabled and disabled.
In doing some research, it seems that Apple did some changes with Lost Mode in 14.6 beta 3.
Can anyone test/confirm on a DEP phone, doing an upgrade from 14.5.1 or prior to 14.6, the device will not be removed from Lost Mode after enabling it, then trying to disable it?
