title: Firebase Authentication fails after publishing App
body: <p>I am using 2 google accounts and 2 different firebase projects for Development and Release for android app.
  I have Implemented Google Authentication on both of them.
  Both operate well when I have the build. i.e Dev also performs Authentication and release build as well.
  When I publish my app on Google Play Console and download it via play store, Google Authentication fails. It gives Error "<strong>Sign In Cancelled! RC: 0</strong>" </p>
