Shopify Marketplace Connect

The most disfunctional experience with an app I have ever had. The Ai bot and I have been trying for two days to connect our shopify store to amazon. Nothing that is supposed to be visible on the app pages is actually there. It is the most non-intuitive app I have worked with. Lost of uneccessary information requested and nothing that we actually need is listed on the pages. It took us 20 minutes to connect using the Amazon Prime app for our US store. I am two days into this for our Europe store and still struggling.
