问题
I updated my Xcode to 7.2. I sent an app build to testers and one tester had the following error:
Testflight could not install app. There was an error with this request
His device is an iPad 2 running iOS 8.3. Deleting the user and reinstalling the app has no effect.
What is causing this and how can we prevent Testflight installs from failing with this error?
