.enableAnonymousUsersAutoUpgrade() problem
Hello, This issue is similar to: Similar to https://github.com/firebase/FirebaseUI-Android/issues/1475
The problem: When enable .enableAnonymousUsersAutoUpgrade() in AuthUI.getInstance().createSignInIntentBuilder(), and after signing in anonymously and then signing with Twitter/Facebook account that does not have an email attached to their accounts, gives an error "Unkown error". However, when signing in anonymously and then signing in with Twitter/Facebook account that has an email attached to them, things work fine.
It looks like enableAnonymousUsersAutoUpgrade() have an issue when trying to upgrade an anonymous account using Twitter/Facebook account which doesn't have an email attached to them.
Steps to reproduce:
- Sign in anonymously
- Sign in with Twitter/Facebook account that does not have an email attached their accounts.
