Deleting the App Catalog
Sometimes it is necessary to un-enroll a device while troubleshooting issues with the apps. Once the device is un-enrolled, it can be re-enrolled to install fresh versions of the apps.
1. From the device home screen, select the 'Settings' app.
2. Go to the 'General' section.
3. Select 'Device Management.'
4. Choose the profile listed.
5. Select 'Remove Management.'
6. Hit Remove again.
7. The app catalog should now be removed from the home screen.
