The App rarely works as expected. Often the locations nearby fail to allow mobile checkout and, worse yet, when attempting to use the in-store coupons the coupon will fail to load roughly 90% of the time and then become unavailable for future use. You find yourself in the drive through, and because you can't queue the coupon up in advance, you end up trying to load it on the spot and are forced to pay full price for your meal when it doesn't load.
