Oops
I read the reviews before I got this app but did it anyway. I bought 4 McCafe drinks and each time my purchase was recorded by having my phone scanned. The fifth scan not only never showed up but apparently erased my others. I sent an email to McDonalds whose response was instructions on how the app works...should work. You think they could at least issue a coupon. So much for my free 6th beverage.
