title: Google Play Referral Flow remains empty
body: <p>As shown here <a href="http://android-developers.blogspot.de/2013/10/improved-app-insight-by-linking-google.html" rel="noreferrer">http://android-developers.blogspot.de/2013/10/improved-app-insight-by-linking-google.html</a> we can now link our playstore apps to analytics and see the Google Play Referral Flow</p>
  
  <p>I linked one of our apps to an Analytics account/property. Still Google Play Referral Flow remains empty even after 2 days of waiting. The App has Google Analytics integrated. Any what could be wrong or missing?</p>
