title: ANDROID 4 KITKAT Code push is successful but the app doesn't update
body: <p><strong>Steps to Reproduce:</strong></p>
  
  <p>Code push is successful.</p>
  
  <p>When opened, the app does not update. Trying to log it produces the error <strong><em>UNKNOWN_ERROR</em></strong> from codepush sync.</p>
  
  <p><strong>Expected Behavior:</strong></p>
  
  <p>Code push should update the app after the user closes the App and restarts it manually. Only then should the update show up in the App.</p>
  
  <p><strong>Actual Behavior</strong></p>
  
  <p>Nothing happens and the app doesn't update. When I use it on splash screen, attempting to load it doesn't work as it gets stuck.</p>
