When a profile is linked to a set of apps, it is linked to specific versions of those apps. When new versions of an app are published, it can leave profiles outdated.
Updating App Versions Across Profiles
Enterprise Device Manager Customers can go to the “Apps” tab in the top navigation menu, select one or more apps, and click the red “Update App Version” button.
There is an indicator on the right of each app that shows if there is an update available for that app, however updating an up-to-date application is harmless.
Note: Devices running a profile with an outdated app version will not receive any app updates until the device is rebooted.
