The app *was* perfect up until a couple months ago. Suddenly every time I tried to redeem rewards, it would say "not available during lunch" during breakfast hour for breakfast items and vice versa. I contacted supported and was told to uninstall, then reinstall. After, I couldn't log in for a month. After a month, I was able to log in again and the same problem happened. Contacted support, same advice or have to call support. Meanwhile my points are all expiring. =(
