The App Profiles page defines app profiles. App profiles determine which apps are required to be installed or disallowed from being installed on managed mobile devices. Each app profile represents a different set of apps. All apps belonging to the same app profile are either required or disallowed. You can assign multiple app profiles to a single mobile device. Changes to a profile affect all devices assigned that app profile. An app profile is assigned to managed mobile devices using Mobile > Assign App Profiles.
If an app is disallowed, Mobile Device Management does not automatically uninstall the app. The user is asked to perform the uninstall manually.
If an app is required and the app is a store app, Mobile Device Management sends an invitation with a link to install the app to device users. If an app is required and the app is an enterprise app, the app is pushed automatically to the device. See Add Master App Catalog Item for more information about these two types of apps.
The list of device IDs you can select on this page depends on the Device ID / Machine Group filter and the scope you are using.
