Why is eBay Product Sync not working when I create eBay listings from ProStores?
Only eBay listing created outside of ProStores (using eBay SYI form, Turbo Lister, Blackthorne or other 3rd party listing tools) are eligible for eBay Product Sync functions. You can edit your eBay listings with an eBay tool, but those changes will not update the product information in ProStores. ProStores product information can be edited independent of the eBay listing created in ProStores.
