title: windows 10 apps DownloadOperation not starting
body: <p>I'm trying to download a file using this code on a windows 10 universal app:</p>
  
  <pre><code>await downloadOperation.StartAsync().AsTask(token, progressCallback);
  </code></pre>
  
  <p>it's working on pc but on mobile sometimes it's doesn't start downloading and not even giving an exception until I restart the mobile.
  Is it a bug in the system or I'm missing something?</p>
  
  <p><strong>Edit 1:</strong></p>
  
  <p>the task's status is "waiting for activation" so it's not throwing an exception.
  it's just waiting and not starting until I restart the phone
  I'm trying always with the same url and I don't have this problem on the pc. It's about the phone only.
  The task's properties are the following:
