1 - It would be great if when I update a Ship to Address on Shopify it was updated on Shipstation when I refresh Shipstation's feed. This would prevent the shipping department from making mistakes, and avoid having to have fulfillment comunicate with shipping.
2 - When a NEW item gets added to an order on Shopify, it would be gerat if it could be reflected on Shipstation. Currently only quantity changes to existing items are, meaning if a customer added an item, when they receive the shipped notification email form Shipstation, it won't reflect the fact that the new item was added, confusing the customer and creating a bad experience.
Pretty much ANY updates done on Shopify should be reflected on Shipstation so that customers and shipping department receive up to date information from Shipstation.
