title: Unable to receive FCM Topic Messaging on iOS 9.2
body: <p>I wrote application which uses FCM topic massaging to receive push notifications from server.</p>
  
  <p>My HTTP request is:</p>
  
  <pre><code>https://fcm.googleapis.com/fcm/send
  Content-Type:application/json
  Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA
  {
  "to":"/topics/Foo-bar",
  "priority":"high",
  "content_available": true,
  "data":{
      "notification-type":"chat",
      "target":"Current User",
      "title":"Current User has sent you a message",
      "text": "hello1",
      "badge": 5  //Badge you want to show on app icon
     }
  }
  </code></pre>
  
  <p>And I got response as:</p>
  
  <pre><code>{
  "message_id": 6199072048907273657
   }
  </code></pre>
  
  <p>But it doesn't receives Notification on device.</p>
