So, I could go to the devices and use this: If an app would like to connect to devices on your local network - Apple Support
But surely there is a configuration policy that I could implement instead? Basically these are restricted kids games station running on iPads and having them connect to other iPads in the building creates a potential behavior problem, bullying, etc.
Would rather when they play Minecraft on these devices, they just have their own local world and nothing else.
