title: External testing on testflight rejected because demo account needed
body: <p>I submitted my app for review to start external beta testing and I got the response:</p>
  
  <blockquote>
    <p>Guideline 2.1 - Information Needed</p>
    
    <p>...but we are not able to continue because we need a demo account to
    fully assess your app features.</p>
  </blockquote>
  
  <p>The app requires verification by phone number (same as when you install whatsapp), and sends a message to the phone number, but there is no "demo account". Do I need to create an account which they can access, with a phone number, and a pre-set verification code in this case? The app is based on the contacts on the phone, so the "experience" won't work as it would for a user this way. </p>
  
  <p>Thanks!</p>
