Shopify Marketplace Connect

This app has stopped us from getting any sales on Amazon for 6 months. Its help center has had 6 months to resolve it and is still unresolved. Their help center keeps saying to reauthorize Amazon, which we have done (more than 20 times) and it still keeps advising the same issue. Our Amazon store is working perfectly. Nothing wrong there, only the app.

My products do not exist in Amazon, it is assumed that new ASINs must be created, now I get this error: include the following attributes: product_type. Feed ID: 0. For more troubleshooting help, see
  the support does not look how to solve it, nor do they look at the emails that I have sent, calling Amazon repeatedly to tell me what is the problem of this application ... if it keeps giving me errors they will block my account ... if you put a negative comment they call you to take it away, but they do not look at what happens or explain anything to you

I installed this app to connect with Amazon.au on my recently launched Shopify store (switched over from Neto) and had no end of trouble. Only about 20 of my 600+ products were successfully synchronizing (all orders were synchronising properly) - so it was clear that the app was connecting to Amazon but Codisto could not work out why the other products weren't synching. I had previously listed to Amazon via my previous Neto store without a problem so all my product data in Shopify and my products in my Amazon account are fine (GTIN, images, pricing etc). Numerous email exchanges with tech support only produced progressively less realistic solutions to solve the problem, culminating in Codisto saying "everything looks fine at our end so there isn't a problem". Which is obviously not the case. Some of the suggestions were to change things in my product data for things that are not even used by Amazon to synchronise listings or were fine when it was Neto talking to Amazon but didn't work when it was Codisto talking to Amazon. Yesterday I deleted the app and installed a competitor's app which works perfectly. A couple of minutes updating settings and within half an hour all my products were successfully synched with Amazon. This shows that the problem was not with my products and not with Amazon - it is clearly a problem with Codisto but they refused to acknowledge it (or their tech support people are insufficiently experienced to resolve the issues they are employed to resolve). I can't fault the tech support people for their efforts to solve the issue but there is clearly something wrong with the software and their training to identify why some items were synching and most weren't (and all my products are the same brand/product type/Amazon category etc so it's not as though my problems were due to variations in what I am listing to Amazon). As a final note, Codisto really needs to install a text chat system or phone clients to talk through the problem in real-time. It is very hard to troubleshoot issues like this via email. (additional comment in response to Codisto reply) Given my products all synched properly previously with Neto and then later with an alternative Shopify app, then there is clearly something wrong with your software. To claim you are confident there is nothing wrong just sums up the problems with your service. Your customer service team is poorly trained and unwilling to acknowledge there was a problem.

This app has published the same items to Etsy several times, I received a huge bill to pay from Etsy for those duplicated listing fees plus the time I spent to delete them from Etsy shop.

Amazing customer service and very easy to use. Has been really easy to set up and I cant wait to continue using Codisto in the future.

the best support from Joy B , i really appreciated
and the app is User friendly , simple
thanks

I had been listing my most popular items to ebay manually and making some sales but now I didn't list more than 2 products from my entire store because it took forever. With this app it immediately found all of my products and let me list them in just a few minutes.

Thank you to the app makers for this one

Best App for synch your order from Amazon to Shopify. I love it!!!
Easy to set up and the support team is very fast and professional!!!

Great! Set up and support team are amazing. I had some questions on implementation and they were resolved within minutes in the instant chat.

Great customer service from Marketplace Connect. Quick, fast and efficient with excellent communications - thank you.
