I am implementing fb login for companies! if the user is added to the role then everything works as it should, but if there is no user then the request is https://www.facebook.com/v19.0/dialog/oauth?client_id=${CLIENT_ID}&redirect_uri=${DOMAIN}/redirects/ insta&config_id=${CONNFIG_ID}&response_type=code says "This application does not appear to be available." The application is in published mode. What could be the problem?
