How to add internal testers with iTunes Connect

Question

iTunes Connect and Test Flight have changed yet again! Does anyone know how to add internal testers?

When I try to add testers I can only select existing testers - but how do I invite new testers that are NOT in this list?

Answer 1

You can add new internal testers to the list in the Users and Roles section of iTunes Connect.

Note that to be eligible for internal testing, they'll have to be in the Admin, Legal, or Technical role. Once you add them in this section, they'll be available for selection in the list of testers in TestFlight.

Answer 2

Current list of roles for internal testers is: Account Holder, Admin, App Manager, Developer, or Marketing role
