Right now, orders that fail to meet Shipstation criteria (e.g. missing postal code, invalid characters in the address) are not imported from Wix Stores and simply 'disappear'. Instead, Shipstation should at least notify me that there was an issue importing an order, and what that issue was, so I can correct any issues on the Wix side before trying to re-import.

Right now the order disappears into thin air. The customer never receives their product. I have no way of knowing this has happened, until our business gets a complaint. You can do better.
