After uploading app I'm getting this error (testflight is currently unavailable). Are you challenging the same problem? Is Testflight really unavailable. I'm afraid there is some problem with my provision profile.
Testflight is currently unavailable
Testflight has been working flawlessly for me the last month... until yesterday. I keep getting errors that Testflight is unavailable. So it's probably not just you. Yesterday I updated my phone to iOS 8.4, so I'm not sure if that's part of the problem or not.
Same issue for me... was working fine, upgraded iPhone 5 to iOS 8.4, and now get the "TestFlight unavailable" error message as well... On iPad that happened to still be on iOS 8.3, TestFlight continues to work fine, so appears to be iOS 8.4-related...
Ditto iOS 8.4...
I'm also having the issue. And my devices are also upgraded to 8.4 recently.
I have same issue with iOS 8.3
Happening in my tesflight, all our devices, different users, and more than one app (two at least from different companies) right now.
