Installed provision profiles not seen on iOS8?
I know this is an old thread. I have been experiencing the sam issue with students downloading apps through 3rd party. The provisioning profiles are still on the device, despite them being removed through settings etc..

Once the update 10.2.1 was complete they no longer exist on the device as seen through the our MDM, Xcode or the device itself.. 

So updating to new OS worked for me.. Hope this helps anyone
