Not found inventory by SKU

This error might appear when you are trying to Update the Linked products. It happens when "Use Inventory API" is enabled in the eBay profile configuration. Inventory API might be used to create products by some apps, for example, by old Shopify eBay app.

Salestio uses Trading API. So in most cases, there is no need to enable this checkbox to run the updates in Salestio.

To fix the error, go to Salestio > Profiles, open the associated eBay profile, and uncheck Use Inventory API. If you do not use eBay profiles as saved template, disable this checkbox in the Selling List settings.
