Wifi only?! App stopped working over celular network since last update. It won't even open, it freezes on the intro logo for literally forever. Will only open if the phone is connected to a wifi network, so haven't been able to use it. Tried connecting to the Dunkins wifi while on tye drive thru but takes too much time. App has an app feedback feature that is also disabled. The app basically doesn't exist unless you are on wifi. Is being weeks with this issue and no update. App Sucks right now!
