Product feeds from Squarespace issue? Having a real issue with uploading a client's catalogue from Squarespace feed. Keeps uploading and then hitting an error with mismatched content ids. From trawling around on other forums I think it may have something due to the feed not reading the SKU and using the Product ID instead. So when an item has different specifications it wont work. But I can't work out for the life of me how to solve this issue? Anyone come across this before?
