Utter garbage.
The mdm server(s) appear to be down or overloaded at the moment. This results in inability to switch controlled devices in/ out of child mode. I have three devices under management and two of them are stuck in "child mode pending" for the last 30 minutes.
Also, by design under iOS even in locked mode some native apps are available- camera, mail, messaging. Lol- those right there are all naughty kids need.
So to sum it up- great idea, lousy supporting infrastructure and iOS restrictions which render app somewhat useless.
