For some unmanaged apps, e.g. Apple native apps Garageband, Numbers, you may need to remove them manually from the iPads.
To remove apps manually, please make sure the following 3 profiles are inactive :
- Disable AppStore/Apps Install/Remove
- Disallow App Removal
- Disable AppStore
If you have set Homescreen Layout, please unset - Devices > Device Management > Action / Bulk Action > Settings > Unset Homescreen Layout
Then you can now manually remove apps from the devices
