title: Firebase Phone Auth not working when published (Android)
body: <p>The phone authentication works when using the debug version of my app and also works when I manually install the release-signed apk on a phone. But when I publish the same working apk to Play Store (Alpha Testing) I can't make it to work. After digging a bit a got this:</p>
  
  <blockquote>
    <p>This app is not authorized to use Firebase Authentication. Please verifythat the correct package name and SHA-1 are configured in the Firebase Console. [ App validation failed ]</p>
  </blockquote>
  
  <p>I know what it looks like. But I can assure I've added the correct SHA-1 into Firebase console and check it before publication.</p>
  
  <p>My questions: <strong>Is there something else I should look at?</strong> I've also double checked the google-services.json with no success.</p>
