For some reason, the Mark As Ready button for On-demand delivery orders alerts the customer rather than the driver or the delivery company (in our case, Door Dash). We had a situation of a small order that was completed before our default prep time, and we marked it as ready. The customer got the message it was ready, and the driver was not alerted and wasn't going to pick it up for another 40 minutes. The customer was very angry, and we had to contact Door Dash to try and get a driver ASAP. We need the Mark As Ready button to alert the delivery company / driver, not the customer.

And after Mark As Ready is triggered, it becomes Mark As Delivered. How would we know when the order has been delivered? We only know when it has been picked up. This On-demand delivery functionality is half-baked. We need some common sense built into this thing... but that could be said for most of Square's products.
