I have 2 problems:
First with Google:
I get an empty response all time when I use "result.AccountInfo.GoogleInfo.GoogleEmail". I connect without problems and see all other data but can't access to the GoogleEmail of the account, I'm forced to get it with "PlayGamesPlatform.Instance.GetUserDisplayName()"
Second with Facebook:
In my Dashboard, I cant see the Facebook id when I link only see "---". In the code is all ok with Facebook.
