title: Google Play Store not showing update button
body: <p>I have a published my App in Google Play Store with version code 4. I made some changes and changed the version code to 5  and also changed the version name and I published the new version through Google Play Store</p>
  
  <p>I can see the new version published but I'm getting <code>Open</code> button Instead of <code>Update</code>
  I checked couple of old questions and none of them gave me the right answer.</p>
  
  <p>Notes:</p>
  
  <ul>
  <li><p>The published APK is signed by Google Play Store </p></li>
  <li><p>The older version in my phone was installed from Google Play Store </p></li>
  <li><p>If I uninstall the old version, Google Play Store gives me the newer on. But I cant force the users to uninstall and re install</p></li>
  </ul>
  
  <p>any suggestions? </p>
