Can't link my Xbox with Facebook "URL blocked This redirect failed because the redirect URI...

Connecting to Facebook is not working. Produces the following error on Facebook:

URL Blocked
This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs.

same question .. cannot use Township

That link is redirecting me to a 404-not found page. I think it is because that page is not available in my language (I am italian, but I can't understand why is redirecting)

I can't remove credit card because it shows that my paypal is linked with Xbox Game Pass and when i'm clicking remove It redirects me to add another payment method

No its not like that. Ok so I am going to play MCPE then when i signed in it says i can't play servers because my privacy settings isn't set up properly and it gave me this link:

aka.ms/account settings

and that redirected me to that support site and i tried editing my xbox account but it always redirects me to that support site.
