I am already testing a build on TestFlight, but today when I uploaded a new build (same app version), I cannot send it to test.
The bundle was uploaded successfully with Application Loader and appears in the list of builds on the Activity tab. Internal tester can install the new build without problems!
However, for external testers, when I choose Add Build to Test I can choose the new build, but on the final page (where I choose if I made any significant changes since previous submission) when I click submit, nothing happens.
It does show a spinning wheel for a second, but the window does not close and nothing happens. This happens no matter if I choose Yes or No to the Significant change question.
I use XCode 7.3.
What is wrong?
Today it worked, and I have two theories about the reason:
1) Yesterday I answered No to the Significant changes question first time I submitted. It could be that Apple detected that I did make significant changes and therefore blocked submission for 12 hours (answering Yes in the following attempts did not work either). Today I answered Yes in the first attempt, and then the build was accepted.
2) Testflight was simply down for several hours. However, if this was the case, I would expect others to report the same problem.
