1. Please access the Gelato shipping profiles from your Shopify account by clicking on Settings > Delivery and shipping > App shipping profiles.
2. The next step is to link the product to the right profile (e.g. let's say it's about connecting an 11oz mug to Gelato shipping profile).

On the next page click on Manage Products.
The window with products will pop up.
You need to checkmark the products that shall be connected to this profile and save changes.
