title: Upgrading billing 2 to billing 3 returning error in production "This version of the application is not configured for billing through Google Play"
body: <p>I have an old app, recently we upgraded from Billing 2 to Billing 3
  everything works fine in test mode, but in production the moment you start the billing flow we get this message &quot;This version of the application is not configured for billing through Google Play&quot;</p>
  <p>** I fully tested in test mode and works correctly
  ** I added my test email to License testing
  ** The APK is signed with the release certificate.
  ** Uploaded the app to closed testing and everything works correctly i can purchase the product</p>
  <p>When i download the app from google play and click on purchase i get the error, when i query the inventory everything works correctly</p>
