Horizon Store review for Shopify Marketplace Connect

DO NOT SWITCH FROM LEGACY CODISTO! It has been nothing but trouble for us for switching to 'new' Marketplace Connect. eBay integration is broken and will not allow you to sync your existing catalogue. I expected better features and support now that Shopify took over Codisto. It is however, downgraded significantly in both areas. The features no longer work. And the support is ridicule as the agents don't seem to have a clue.
