Thanks for your suggestions. We are pleased to announce we have begun development on a feature that will allow tracking information and text to be passed back to WooCommerce via the ‘notes’ field on orders.Alan commented
Please Integrate tracking information with Woocommerce as it is with eBay and Amazon. The automatic uploading of tracking numbers is an absolute must. The widget already exists within Woocommerce, they are simply waiting for Royal Mail to enable communication with the "shipment tracking" extension.
