Hello,
Welcome to our Microsoft Q&A platform!
The Xamarin.Auth library has not been updated for a long time. For the authentication in Xamarin.Forms, try using the Essentials.WebAuthenticator library.
var authResult = await WebAuthenticator.AuthenticateAsync(
new Uri(Authorization URL ),
new Uri(Redirect URI);
var accessToken = authResult?.AccessToken;
Best Regards,
