title: Azure Notification Hub: notifications not showing up if sent to group
body: <p>I have a trouble making notification hub to work. </p>
  
  <p>If I send notification to tag that has only one registration associated with it, then everything's fine. Here's source:</p>
  
  <pre><code>var alert = "{\"aps\":{\"alert\":\"some message(targeted)\"},\"inAppMessage\": \"text\"}";
  hub.SendAppleNativeNotificationAsync(alert,"mytag").ContinueWith(t =&gt; {
      var outcome = t.Result;
      Console.WriteLine(outcome);
  });
  </code></pre>
  
  <p>But if I try to sent my notification to all users, like so: </p>
  
  <pre><code>var alert = "{\"aps\":{\"alert\":\"some message(all users)\"},\"inAppMessage\": \"text\"}";
  hub.SendAppleNativeNotificationAsync(alert).ContinueWith(t =&gt; {
      var outcome = t.Result;
      Console.WriteLine(outcome);
  });
  </code></pre>
  
  <p>then no one gets the notification. I checked monitor in Azure portal but there were no errors present.</p>
  
  <p>Do you guys have some ideas?</p>
