I have tried the Mobile App numerous times over several (10+ months) and the app gets the point when it charges your credit card to finalize your purchase, then a white screen appears, and the purchase never completes! Then, you have to back out the be able to use the coupon deal "Use at the Restaurant," and a 7-minute delay occurs before the coupon code will appear for you to use in the drive thru. We had to make three circles of the drive thru line before the deal code finally opened up. Sad!
