Hello. Please implement passing Etsy Gift message to FBA "Packing slip comments" field. This will help very much. All the Gift messages Etsy buyers are leaving now, are just ignored by Shipstation. It receives the message with an order from Etsy, but is not passing it to FBA for fulfillment, and to include in the packing slip.
Manually it is possible. And automatically via Shipstation, it looks like there is only one simple step is missing.
