title: Google play game service "Failed to sign in.Please check your network connection and try again"
body: <p>I just released my app on google play. When the app tries to login to google game service, I get an pop saying "Failed to sign in. Please check your network connection and try again". I have been able to login during the development of the app. </p>
  
  <p>In google developer console, I have linked both the debug and release version of my app. </p>
  
  <p>One thing that might be the problem is that I published the app before the game service (which is not recommended by google). Is this the problem? How do I fix this? How can I debug this?</p>
