The app does not work I think they do it on purpose so that you won't get your rewards points especially after you've got your first free pizza they don't want you to get another one the app does not work it is you sign in and keeps telling you to sign in they have to go back and then it tells you after you change your password it tells you that it is invalid then I changed it again it does not work very frustrating but again I say it's because they don't want you to cumulate points
