Very disappointing app. Used to work just fine then several months ago it gives a JSON parse error every time I try to login. Have rebooted my Android device, uninstalled, reinstalled, force closed the app, uninstalled, rebooted, reinstalled and it still does not work. The Dominos app works just fine. I can recommend the Dominos app without reservation. Pizza Hut, not so much. I hope one day they are able to resolve the JSON parse error because I do enjoy their pizza and wings, but not the hassle. At least I can still earn rewards by using my laptop to place an order.
