Can the internal tester in testflight use the build even if he is removed from the testers list?

Question

I have uploaded a build to TestFlight and we have 3 testers in it and they have installed the app in their devices via TestFlight invitation. Now i am planning to upload another build but this build should be available only for 2 testers so i am planning to delete one tester from the TestFlight testers list for this specific app. We are not deleting the tester from our iTunes Connect Users List. If i am trying to delete tester from the list it is showing the below message.

So my doubt is, if i am deleting the tester from the list whether he will be able to use the app which is already installed in his device from testflight. I want the tester to use the app.

I am aware of creating groups in testflight for testing but we can only create group for external testers, we cannot create a group for internal testers. Any help will be really appreciated.

Answer 1

If they have the app already installed they will be able to use it since it is not launched via TestFlight. What they won't be able to do is to download new versions or use it after it expires.

You can read more about how TestFlight policies work here, and here there is a discussion about expired builds.
