title: Issue: Need login credentials for app review
body: <p>I've been trying to publish an app now for almost a month now. But I always get a reject from Google that <em>credentials are required for app review</em>. I am using Google Sign In as the only log in method, I already described in the <strong>App Access</strong> module in Play console that all users need to sign in with their Google account.</p>
  <p><strong>Edit:</strong> I created a test Gmail account and provided instructions together with the password via the <strong>App Access</strong> module but still facing the same issue.</p>
  <p><strong>P.S</strong> Crazy thing is that all my other published apps are all using Google sign in and have never faced this issue before. This inconsistency from Google at times can be nervewrecking</p>
