You can monitor the status of the app protection policies that you've applied to users from the Intune app protection pane in the Azure portal. Additionally, you can find information about the users affected by app protection policies, policy compliance status, and any issues that your users might be experiencing.
There are three different places to monitor app protection policies :
* Summary view
* Detailed view
* Reporting view
The retention period for app protection data is 90 days. Any app instances that have checked in to the Intune service within the past 90 days is included in the app protection status report. An app instance is a unique user + app + device.
