Got a rewards card and installed the app. Went through registration process and could not login to app or website (does not recognize me). Called Guest Services (only support option available). He found my info. "Don't use auto fill." So I didn't use auto fill. Still have worthless rewards card and worthless app. Oh yeah.. there was the awesome suggestion to try again with another email address. But hey... Guess what??? That card is registered to the first email I started with. Good job fellas!
