title: iOS push notification not working on app store build where as working on test push
body: <p>This is regarding a push notification services.</p>
  
  <p>One of my app is not receiving push notifications after an update which it was receiving before the update. I have tried all the troubleshooting techniques provided by apple and resubmitted the app as well but helpless.</p>
  
  <p>Following test cases I have executed.</p>
  
  <ul>
  <li>Renew the Push certificate and updated PEM file with server.</li>
  <li>Re submitted the app by validating distribution profile and push certificates.</li>
  <li>App is not supporting iOS 10 upgrade, So entitlement file is not added in build.</li>
  <li>Server receiving a token from the App successfully and notification feedback also succeeded.</li>
  </ul>
  
  <p>Back end server run on Ruby on rails using APN_on_rails GEM for push.</p>
  
  <p>My only concern is I am getting push notification in my app(downloaded from App Store) when manually sent as test badges from the same server but same is not getting pushed when sent from live scenario.</p>
  
  <p>Post if you need any other details to look into this further.</p>
  
  <p>Please help me on this, Thanks in advance.</p>
