Description
This works only with supervised devices (MDM) and allows Apple Game Center to be disabled. The rationale is Game Center is using Apple ID and will share data on AppleID-based services; therefore, Game Center must be disabled. This setting also prohibits the functionality of adding friends to Game Center.
