Restrictions Configuration

These features only work if you have an Android Enterprise bound to Liminal EMM. For more information, see Android Enterprise Settings.

Use restrictions to enforce security and permission policies on devices and to control device functionality.

This configuration can be set at the organization, site, or group level. If a configuration exists at multiple levels, devices will use the configuration at the lowest hierarchical level they belong to (group > site > org). If a device belongs to multiple groups, it will use the configuration that was most recently applied. For more information, see The Liminal EMM Hierarchy.
