Update 2022: well the app seems to work out right McDonald's themselves have made it slower to utilize it. They don't even start making your food till after you arrive at the store. Next time take note at the cars in the Drive-Thru and notice the car's pulling in after you've already parked and placed your order will get served before you. This has happened to me 5/5 times I've used the app. I recommend spoofing your GPS and say you're at the store a few minutes before you actually get there.
