Sublimation Blanks UK review for Shopify Marketplace Connect

It doesn't work properly. I have connected my Shopify with eBay account and some of the items on Shopify have sold out but they are still showing as available on eBay. I have deactivated an item on Shopify and manually removed it from eBay as it did not get removed automatically and it kept getting re-listed for some reason so I had to keep removing it until I was forced to permanently remove the listing from Shopify to stop it from being re-listed on eBay
