Shopify Marketplace Connect

Works fine for ebay but not Amazon. I've been put through the wringer with this company and have been with them for 12 months so it's not a knee jerk reaction but MarketPlace Connect simply does not do what it says.

I keep being told developers are looking into it but it's not solved. I don't believe they have the technical skills because simple listings do not sync with Amazon and are stuck in publishing mode. I've waited 2 months for this to be sorted but run out of patience. I absolutely do not recommend this app for Amazon syncing.
