Where is redeem code for public link for TestFlight?

Question

Sent public URL to a user, and he reported TestFlight does not show the app, but asked for a redeem code? Where can I or he find this code?

Answer 1

The redeem code is sent by mail when you add an external or internal new tester in TestFlight.

When you open your app in App Store Connect, go to "My Apps" and select your app. Then go to the "TestFlight" section, complete the "Information" section, and then add external testers as needed and the build to test.

After this Apple sends emails to all testers with the invitation.

A good tutorial on TestFlight can be found on raywenderlich.com.

Answer 2

This issue is happening to me also. Some customers are saying they are asked to enter the redeem code while using the public link for downloading the app from TestFlight, so they are unable to download the app.

Workaround was to add the user's email id to the test group so it will send email invites with redeem code.

But I still do not understand why the public URL for downloading the app is asking for a redeem code? And what will be the redeem code for people using the public link? Another interesting thing is it's happening only to some users.
