I am encountering the same problem : Same objective (social login only), same attempt in copying the Authentication/browser flow + disabling the browser form ==> Same error in return : “We are sorry …”.
Hiding from the html template seems definitely not an acceptable solution to me.
So would be interested also if anyone solved this issue
