apparantly Apple changed the URL for Apps in their App Store from "https://itunes.apple.com/" to "https://apps.apple.com/"
for example the URL for the Intune Company Portal changed from https://itunes.apple.com/us/app/intune-company-portal/id719171358 to https://apps.apple.com/us/app/intune-company-portal/id719171358
So far no problem - but when using an iOS Device Configuration Profile which configures Devices Restrictions -> Restricted Apps, the new URL does not work and fails to apply on the devices.
Apple Support said it's not their issue but Microsoft's....
Anyone any idea besides just swapping "apps" with "itunes" when creating the profile?
apparantly there was a misunderstanding of how profiles works with one of my colleagues, it works just as i said it would and is documented here in the blue box: https://docs.microsoft.com/en-us/intune/device-restrictions-ios#show-or-hide-apps-supervised-only
Thread can be closed if there's such a thing here :)
