If it appears that nothing is crossposting from eBay or during the crosspost it appears that the process stops when opening an eBay tab please confirm if your listing on eBay has been created with eBay’s “new listing tool”. Below is a screenshot of what that listing page may look like when editing your product. At this time List Perfectly does not support this new layout. You can switch to the “original listing tool” by selecting the option at the top right of your listing form.
