title: Amazon SNS delivery receipts: do they indicate delivery to mobile or delivery just to the push notification service?
body: <p>I want to know whether AWS SNS (Simple Notification Service) delivery receipts indicate:</p>
  
  <ol>
  <li><p>whether AWS SNS delivered the push notification just to the relevant push notification service (e. g. GCM, APNS), or</p></li>
  <li><p>whether the push notification was actually delivered to the mobile phone of the targeted user</p></li>
  </ol>
  
  <p>The documentation appears vague on this.</p>
  
  <p>I'd also like to know if, in case the second case above is true, whether the delivery receipts are also delivered when the app has been force-killed by the user.</p>
