(empty) username using react native login with facebook

Hey!

I 've successfully implemented native login with facebook using react native. Everything is okay, however, when i go to the auth0 dashboard, the user that logged in with facebook is (empty) even if i send the user details with user_profile in my /oauth/token request. I think it should load my profile picture and name in the dashboard. I have already enabled email under connections and public profile Any ideas?
