McDonald’s app and self service kiosk issue.

Using the app voucher to purchase a big Mac meal via your “easy” to use order points so that you don’t have to order from the counter was not so easy as you don’t see anywhere where it says click on offers to redeem app qr so by the time I got to checkout and was not asked to scan my qr code I had to cancel the order and then my qr code disappeared and now it says I have to wait till tomorrow’s to qualify for the same qr code that I didn’t even use. Wasted my time and fuel to come grab a nice bite to eat but after this experience I will never support MCDonalds again. Burger King is way better anyways.
