Every time I've used this app I've had issues. The first time I had to sit in the drive thru for almost ten minutes as the cashier and manager tried to figure out how to get it to work, the second time I I was charged IN FULL for an order that I should've gotten for free, and the third time the QR reader had to be read like 9 times. This app is a massive headache and the only reason I use it is because the deals and rewards do save you a lot of money, when they actually work.
