Shopify Marketplace Connect

Initially functioned well but then realised that it reset almost every product in my ebay store to category "other". I have over 1,000 products and my visits on ebay dropped to virtually zero. Took some time and hair pulling to get everything sorted again using the bulk editor in Marketplace but there are still a lot of missing parameters between the two - expect to invest some time afterwards. The shipping and stock control aspects seem to be working fine.
