itunes install ipa, and icon disappears?

to me the icon disappears during installation IPA via itunes

Have you confirmed that you have a valid provisioning profile for that device?

You might also want to see if you can see anything in the device logs when that happens.

Yes, I confirm that I have a valid provisioning profile for the device.

I use Xamarin on Visual Studio, and I always generated the ipa file you were installing correctly, but since I updated Xcode to 8.0 the problem began.

I tried to recreate the provisioning profile, but the problem remains.
