Answer 2

Maybe this will help someone. It sure kept me busy for a while, and itunes support gave me the solution.

I am running TestFlight 1.0.2 (55) on my iPhone 5S with IOS 8.1.3 (12B466). I was unable to open my app for testing in TestFlight when clicking on the "Open in TestFlight" link. Apple gave me the following 2 steps that solved my issue

2. Click on the "Open in TestFlight" link from the Apple Mail app, not Gmail or something else

I did factory reset and reinstalled my last backup, that worked.
