Expected Results:

• What did you expect to happen?
• Should work normally.

Relevant Information:

According to this Stack Overflow thread,com.google.android.gms:play-services-auth of version 21.2.0 no longer uses Credentials API. Mitigation for now is downgrading to version 20.7.0.

@argzdev Thanks for reporting this. The Firestore quickstart uses the Firebase UI library, which has a bug that I haven't been able to prioritize 😓 : firebase/FirebaseUI-Android#2158

Mitigation for now is downgrading to version 20.7.0.

Would you like to send a PR pinning the version in this quickstart as a temporary fix for now? We can remove the pinned verison once that bug is fixed.

Hey @thatfiredev, totally missed your reply! @lehcar09 will do the honors for the PR.
