As of the week of Nov 26, 2018, you can remove any app on corporate-owned supervised iOS devices. You can remove any app by targeting either user or device groups with an Uninstall assignment type. For personal or unsupervised iOS devices, you will continue to be able to remove only apps that were installed using Intune.
Does this fill the request, or do you need to be able to remove apps on personal or unsupervised devices?

Cathy, so this Uninstall assignment should allow stock iOS apps (e.g. Photo Booth or TV) to be uninstalled on a corporate-owned supervised iPad - correct? Because this isn't working for me and other documentation (https://docs.microsoft.com/en-us/intune/apps-deploy) still says it only works if the app was installed via Intune.
