MobileGestalt no access to InverseDeviceID

Question

This happens with every app when I try to use OpenGLES on my iPhone7+ with iOS10.3. But it works without any problems on my iPho

Answer 1

I can see where the setting up of a sandbox account might do the trick, but if the device you are using is also connected to your normal icloud account, you can't create a sandbox with the same AppleID. You then have to log out of your existing icloud account, and log in with the new icloud (sandbox) useid. Which screws up your existing icloud device settings. So you are unable to use your Developer ID, only your Sandbox ID.
