The app is obnoxiously slow. Many times it refuses to let me finish and pay for my order. Other times it will not let me remove an item from the order or when I go into the restaurant to get my food after the order was placed the store doesn't have it in their system and I'll have to show them the email of said order. A few places said the email isn't enough. That I could've already gotten my food and trying to get more for free.
