McDonald's

For the last three weekends I was unable to order a Frappe on the McDonald’s App at the store on the China Spring Rd in Waco, Tx. It was incorrectly listed as unavailable. Each time I was able to order the frappe at the store but not on the app. I usually use the 20% off deal but for my other items but end up paying full price for the frappe. Please fix this in the app! Employees at the store say it’s beyond their control.
