Missing a shopping cart function to complete purchase. If I make a mistake, I should not have to start all over. I literally have to wait for an invisible timer to expire to start over and select the same movie and seats to make my purchase. Although I could pick another seat, I shouldn't have to. I should have the option to purchase the original selected seats. App definitely needs to have the cart option to expedite the purchase. Customer svs was not very helpful as well.
