Facebook login doesn(t work on mobile

Hi Team,
First, thank for your work. I set up a professional network for a client and he is very happy. Kleo is a great theme !

We encounter just one major problem : our facebook login doesn’t work on mobile devices.
I follow the instruction : https://archived.seventhqueen.com/kleo/article/setup-facebook-login-fix-facebook-login

But we (and our users) encounter the same issues on mobile :
“Unable to load this URL: The domain of this URL is not registered in those of the application. To import this URL, add all the domains and subdomains of your application to the Domains field of the application settings.”

Traduction from the french message

“Impossible de charger cette URL: Le domaine de cette URL n’est pas inscrit dans ceux de l’application. Pour pouvoir importer cette URL, ajoutez tous les domaines et sous-domaines de votre application au champ Domaines des paramètres de l’application.”

Url form the message windows error : https://m.facebook.com/v2.12/dialog/oauth?redirect_uri=https%3A%2F%2Fwww.timefunding.cc%2F&client_id=1623490081023150#&scope=email&response_type=token

Can you help us with that issue ?

Kind Regards,
Kevin
