title: Error DF-DFERH-01 when update the app on Google Play
body: <p>I had uploaded an app on Google Play, it used to be available. But after updating, error <code>DF-DFERH-01</code> occurs for many users of my app. I <a href="https://stackoverflow.com/questions/12812822/google-play-error-error-while-retrieving-information-from-server-df-dferh-01">cleared cache of Google Play</a>, and <a href="https://stackoverflow.com/questions/46265360/google-play-store-users-cant-download-app-because-of-error-df-dferh-01">also set a privacy policy in the settings of the application page</a>, which didn't help.</p>
  
  <p>How can this problem be solved?</p>
  
  <p>P.S. Other apps are updated without errors.</p>
  
  <p>P.P.S. This problem is for all users who use my app</p>
