title: App Rejected with iOS IPv6 network
body: <p>Yesterday, I submitted my app for review, but I got this message from Apple:</p>
  
  <blockquote>
    <p>We discovered one or more bugs in your app when reviewed on iPad iPhone running iOS 9.3.2 on Wi-Fi connected to an IPv6 network.</p>
    
    <p>Specifically, upon review we have found the application still experiences a loading issue and unable to review the application content.</p>

  <p>My app uses ionic framework, how can I fix this problem?</p>
  
  <p>I already used domain to access my server, but this problem still exists.</p>
