When I get local data so I can login to twitter, The auth value is always Not Authorized.

when I debug it ,it works fine , other than that ,it doesn't work. It looks like there is kind of a delay or asnyc issue.

PinAuthorizer auth =
new PinAuthorizer
{
Credentials = new LocalDataCredentials()
};

if (auth == null || !auth.IsAuthorized)
{
Frame.Navigate(typeof(OAuthPage));
return;

Do you know if there any solution for it.

Thanks,
Ramez
