Note: If you previously used the bundle ID (com.microsoft.splists) to add Lists manually, the bundle ID is hidden and the app is now listed as a selected app within the public apps section of the policy. If you attempt to create a new policy and try to add the bundle ID manually, the MEM admin center will notify you to use the public app instead.
