If I go to
www.continental.com, it asks me to sign in on the “preview page” but then says it could not process me because I was not invited.
It makes it also look as if I have not signed in to the regular page.
And it won’t take me to that page.
But I can click on “sign in” on the button at the top of the page that has just rejected me.
But then it turns out I am already signed in to the Preview Page!!!
Go figure!
