I have a Amaszon Seller central - It is integrated with Shopify for sales but when I try to set up my Amazon pay on Shopify It asks me all of the questions including the name of my store. When I enter my store name it says it is taken. I have watched the video on how to sign up. I have start by signing into Amazon seller central.
Why does it not pull my information over or all me to connect to the store I have set up?
