Now you can use product handles when exporting and importing product reference metafields. This will make it easier to see things visually and to transfer metafields between different stores (like a development and production one).
Previously product reference metafields were exported in the native Shopify format which looks like gid://shopify/Product/123456789
but now you will see the product's handle in the exported spreadsheet. This applies to metafields that are lists of product references as well.
For spreadsheet edits, the app will accept either product handles, or the values in the native Shopify format.
