What happens when I manually change a listing on eBay?
Simply put: You’re not supposed to do that. WP-Lister won’t get notified of your changes and will even overwrite them if you revise the listing from WP-Lister!
You have to keep in mind that when using WP-Lister, your WooCommerce catalog will become your “central database” where you should apply all your changes and where you create new products. You shouldn’t have to visit the eBay website anymore once you started using WP-Lister – at least not on a frequent basis.
