I do not know if the problem I have is relevant with the Magento upgrade but I have to mention it. So, I have a Magento 2.4.2, with M2E 1.14 I am trying to add a new listing to Amazon. The product I am trying to list has been bound with an existing ASIN and I get the following error. "Item was not added/updated, Product Data Nick is not valid." Do you have any idea how to solve it ? Thank you for your time anyway.
