Intune can't uninstall apps that are installed from Apple App Store
This article gives a workaround solution to help you uninstall free apps in Microsoft Intune that were installed from the Apple App Store.
Symptoms
An iOS device that's enrolled in Intune contains some apps that are installed from the Apple App Store. For example, non-VPP paid apps. In this scenario, these apps can't be uninstalled by using Intune.
This behavior is by design. Intune can uninstall only apps that are deployed through the mobile device management (MDM) channel.
Solution
To work around this issue, follow these steps:
Add the apps to Intune, then assign the apps as Available or Required.
Note
After the apps are assigned, you are prompted to allow Intune to take over management of the apps on the device.
When you uninstall an application from a device enrolled using Device Enrollment Program (DEP) as supervised mode, you aren't prompted to take over management.
To remove the apps from devices in the assigned group, change the assignment type to Uninstall.
Note
Depending on the installation type and number of devices, it may take some time before you can safely change the assignment type to Uninstall. Use a phased approach, if it's necessary.
