Updated 9/11/24: We recently posted IT862136 on your Service Health Dashboard (SHD) that we identified an issue where newly added apps weren’t targeted automatically in Microsoft Intune app protection policies (APP) when the policy was targeted to app groups such as "All Apps" or "All Microsoft Apps". We validated and deployed a fix to all customers to resolve this issue, and all newly added apps are now properly targeted in APP policies.
If you have any further questions or comments for the Intune team, please send us a message or reach out to us on X @IntuneSuppTeam.
