Aside from obvious glitches and extraneous steps that are unnecessary and add to order completion time, the system in general is flawed. 3rd party batch-grabbing apps are out of control and customers simply claim missing items with no proof to get free items, leaving shoppers fighting to prove their own quality. I also used the actual order app for the first time recently and it is very unclear that the rating you give after is OF THE SHOPPER - which directly affects batch availability/income.
