Question

I want to test application in my device as an internal tester in iTunes Connect. As per new rule to install application through itunes testflight services, I installed new TestFlight native app in my device. And i got one invite as an internal tester.

Now i got one invite to test an application through Email like this,

Now i try to install this app by pressing the button "Open in TestFlight". Now its redirect to AppStore Like This,

Now i press "Open" button, its redirect to testFlight but it doesn't display installation screen of that application. It display like 1 st image i shared in this question.

This is first time am trying to install app from new testFlight. So Please give me some ideas to install app in itunes testFlight.

Solution

I was also experiencing the same issue once But later I fixed it by following this.

1. Make sure you have iOS 8.0 or above

2. Make sure you have installed the latest testflight app and you have logged in using the correct apple id

3. Make sure you are not using Gmail app to accept the iTunes Connect testing invitation.

4. IMHO

   • Always open the invitation from baked in Mail client of iOS or

   • Accept the invitation from webmail using safari or

   • Copy the link of acceptance from the mail and paste it into safari directly

Here is a wonderful link related to Apples new Testflight beta testing it covers from A to Z in simple words.
