title: App doesn't appear on iTunes file sharing
body: <p>I'm testing an app by means of TestFlight.</p>
  
  <p>In the app I've enabled file sharing and when I connect my iPhone I can correctly see the app in iTunes/File sharing section.
  The problem is that I've asked to one of the testers to send me some log files but he says he cannot see the app in iTunes/File sharing.</p>
  
  <p>Is there any reason why I can see the app while the tester not?</p>
  
  <p>Thanks,
  Corrado</p>
