On Xamarin.Forms is possible to verify if user is logged-in without opening the browser view?

[Frank4220]

I tried to call Client and LoginAsync but I'm not able to check if user has already logged in without opening browser.. Is this possible?

If I open browser with _result = await _client.LoginAsync(new LoginRequest()); and user is logged in, it closes immediately after without asking for anything and goes to the main page.. is correct but I think is possible this kind of improvement..

Thank you in advice!
