If I could give it a zero, I would.

The app is completely unreliable. In the last few weeks I have had to deal with the app crashing when I get to the store. And employees are often not willing to honor the coupons. Its really frustrating because most people see the great coupons and want to go to McDonalds because of that. But then when you get to the counter and the manager starts arguing with you saying its not his fault, thats where I draw the line. The cashier even admitted that they were having problems with it all day. It was not user error. The app was not working. This app used to work flawlessly. And now it is a piece of junk.
