Frustrating and difficult. I have to constantly log back in while on the app, that's if and when the app doesn't decide to crash. If it's a good day I can perform the functions I need to but it will take a lot of my patience and spare time. The app can be deceiving as it may give you certain options or discounts on an order and then take them away at check-out. It would help to have consistency since Verizon Up is useful. If I didn't have to use this app I never would.
