Its ashame really

My mom and I tried registering and then logging into the app and it would not go through at all. We heard there was free ice cream today but we couldnt get it since the app wasnt letting us register/login. Very disappointed I feel like this app needs an updated and to be fixed. It would been very nice if it wud let us at least register/login but no it didnt allow us. Other people to maybe complaining about the same issue. Please fix the app
