Multiple items in Shopify order NOT CORRECT
When a customer changes their order in Shopify it still shows both items in the order even if one has been removed!!!!!!!!

Thank you for your feedback! We are currently working on improving how ShipStation updates modified orders for our Shopify users.
We have a feature that we are currently testing around this functionality. If you’d be interested in trying out this feature, we can enable it for you upon request. Please contact our support team and request we enable the Shopify Line Item Adjustments feature.
