We have had quite a few incidents, where our customers have placed items into their carts and the item has become out of stock before they have paid for the order. One item was out of stock since December 2025 and was purchased this week 22nd April. This item was no longer available and was not well received by our customer. It did not look good for us either. Would it be possible to update the cart before payment can be made to ensure out of stock items cannot be purchased or paid for
