title: Android firebase Google sign failing on Production but working on signed apk
body: <p>I am working on an app that I have integrated Google firebase sign in. </p>
  
  <p>On my firebase console, I have two SHA-1 certificate fingerprints:</p>
  
  <ol>
  <li>Debug key</li>
  <li>Key Generated by keytool </li>
  </ol>
  
  <p>I synched google.services.json  with the app and generated a signed apk using Android studio.</p>
  
  <p>Also in my play store console, App signing is enabled.</p>
  
  <p>The problem is that when I use the app downloaded from play store, sign in fails. It only works with the release I have on my computer. </p>
  
  <p>What could be the issue?</p>
