PnP ASAP - Pathetic Inventory Management

On the ASAP App they keep showing items that aren't available, and this is before the day has even begun. Even worse is that AFTER I get the out-of-stock statuses, I can STILL find the items shown as available in the app, and I even managed to add 20 each of them. To make matters even worse, there is no option to cancel once SHOPPING has started, no option to cancel an order where less than 50% of the requested items have been shopped, no compensation for the inconvenience caused AND THEY STILL DON'T EVEN UPDATE THE AVAILABLE INVENTORY after all of that. Nothing they can say or claim about this will explain how a customer can be told items are out of stock in one order, then literally still see them in stock afterwards + be able to order them. It borders on **** behavior
