Since upgrading to iOS 6, I have not been able to install the TestFlight Access profile, and my clients running 6.0 experience the same problems. I have a problem with googled, but I cannot find any results.
An error message immediately after entering the device password and:
"Failed to complete profile installation. A network error has occurred.
I confirmed that I have a good network connection and the error occurs in several physical places (different service providers and Internet access).
Thanks in advance!
