We are using Amazon FBA to fulfill our orders. If a product is out of stock, the order will automatically fail with Shopify. In this case, we'll just fulfill the product manually -- but we need to be notified somehow of the failure (Currently, there is no indication on the Orders page that anything is wrong. You have to click into the order to see the failure).
Is there a way to be notified via email when an order fails? Thanks in advance.
