Is anyone else having the exact same problems I listed? The iOS app receives inbox messages and a notification of every purchase I make with the Windows Mobil app. However, I still haven't received a notification or inbox message on my Starbucks Windows Mobile app. And, as I mentioned before, when I tap on history, the app crashes. Also, there is no clear indication that I earned a reward. They just tallied the number. Unless, the dim brown star means I earned one. (I was looking for a bright [lit] gold star.)
I reinstalled it for the second time and fortunately for the last few days, I've remained logged in, but the other issues still exist.
