I am trying to use TestFlight (new) to share my application.
Now I shared it with my three internal testers on itunes connect , one of them all works fine, and they successfully downloaded the application.
But the other two, when in the TestFlight application get this page:

Why does this expire me, it makes no sense, since it is definitely related to the 30-day test period, since it works fine on another internal test. Any help would be great.
Update
I just received an email from the App Store Developer Support Team
They said:
Hi, Max,
We believe that this problem has been resolved. If your testers are still unable to test your application when using the TestFlight version 1.0.1 application, let us know.
Respectfully,
Ben
If someone still has a problem before , they will try to answer below and after , they updated the TestFlight application. Let me know and I will return to the App Store Developer Support Team.
