I've used a lot of buggy food apps, but this is by far the most frustrating. It's laggy (on a Samsung Galaxy S21), it gives error messages that have nothing to do with what you're doing, and the Deals don't work more than half the time. You're basically forced to use the app to get any decent deals anymore, and as a result I've nearly stopped going to McDonald's entirely. Every time I do, I wish I'd gone somewhere else.
