Store data separation

Listings, images and image order, policies, orders, messages, cases, campaigns and marketplace identifiers belong to their store. Editing one store does not automatically copy those values to another.

Inventory Sync is a deliberate exception for quantity: you configure which stores to compare and review supported quantity changes. It is not a general synchroniser for titles, prices or other fields.

Mac and Web keep separate connections and data, even when you connect the same eBay account to both.
