It seems to me that the new TV app in iOS 11 has hijacked Bundle ID (com.apple.videos), thus orphaning the Videos app. Anyone else seeing that?
I thought this happend with iOS 10. I know it was using that ID because I remember restricting it.
I'm just setting up our new JMAF installation, and noticed the same thing - iPads are on 10.x, Videos app is in a folder (put there by Home Screen Layout), when I upgrade to 11.x the Videos app is out of the folder. Did you find a workaround?
