Bug in iTunes Connect preventing TestFlight submit I have an issue submitting an app build for review in TestFlight.
(Yesterday, a new version of TestFlight was released in iTunes Connect, this might have caused the issue)

Steps to Reproduce the issue:


Log in to iTunes Connect
Select the app
Go to tab 'TestFlight'
Click a build (in this case, 1.0.1)
Click the '+' sign next to 'Individual Testers'
Select 'Add New Testers'


Expected behavior: screen to enter information of test users
Actual behavior: loading spinner is displayed and web inspector console displays error:




Anyone else experienced this issue? I can only reproduce it for one of my apps. It seems to be some bug on Apple's part, and I have reported it, but no answer until now :-\
There might be a problem with iTunes Connect.  I just got an email from Apple about upcoming maintenance: 


  On April 22, beginning at 7:00 a.m. (PDT), iTunes Connect and related content delivery services will be unavailable for up to eight hours.  The following services will be affected:
   - App build upload in Xcode
   - Application Loader and altool
   - iTunes Connect
   - iTunes Connect Mobile
   - iTunes Producer
   - Transporter


Maybe wait until after the maintenance is over and try again.
