title: I can't add testers to iTunes Connect: Users and Roles → TestFlight Beta Testers → Internal
body: <p>I'm a developer for a small company's team. I am trying to set up Apple's TestFlight service.</p>
  
  <p>I have a Beta submitted for a new release. I have turned on TestFlight testing for this build. However, when I try to invite testers, I am told that I need to enable some users for this role. </p>
  
  <p>When I go to the "Users and Roles – TestFlight Beta Testers – Internal" section of iTunes connect, I see the list of other people in the company's team. There is a check mark to the left of each person to select them. iTunes Connect won't allow me to select any of the users and doesn't give an error.</p>
  
  <p>How can I add testers?</p>
