title: TestFlight public link doesn't accept new beta testers
body: <p>I created a public link for a group of testers but the link shows: "<strong><em>This beta isn't accepting any new testers right now.</em></strong>"</p>
  
  <p>The build has been approved and I set the limit to 10 testers.</p>

  <p>Why is the public link not accepting new beta testers?</p>
