Shopify has implemented a new option to edit orders for things like wrong size, wrong item, add an item, etc. Currently, Shipping Easy leaves the added item as unfulfilled and does not close out the order with the shipping information.
It would be very helpful if the order would get updated within shipping easy so that it could properly close out in Shopify.
In addition to ShippingEasy not being able to communicate back to Shopify that an order has been fulfilled (therefore leaving it marked as unfulfilled in Shopify), it also appears that any order edits made in Shopify are not recognized in ShippingEasy - therefore, ShippingEasy ends up fulfilling the original, not the edited, version of the order. Canceled orders and address changes migrate over, but nothing else - so any edits to the items purchased do not get updated.
