CORE Action Sports review for Google & YouTube

Does not sync barcodes to the merchant center. This alone renders this app almost pointless, a shopping feed without barcodes...ALL of my barcodes are filled in on Shopify, it does not sync the field. I have tried multiple hacks and fixes to work around this, but nothing works. Thousands of people seem to have the same problem, amazed it's Shopify own developed app. For extra credit, When you manually add them in the google merchant center, Shopify then wipes them.
