Hi @voilechic ,
Thank you for reaching out to the Community! I’m happy to provide some assistance with selling on Amazon, to ensure this gets resolved.
While the Amazon Sales Channel has since been deprecated, you can look into adding the app Amazon by Codisto to continue selling on Amazon via Shopify. This is our third-party partner app that provides an improved product management as well as additional access to more selling options that the Shopify Amazon Channel did not include.
For more information on the app, you can head to the Shopify App Store and select Support > Send a message. This will put you in touch with the app developers directly to answer any additional questions you may have.
Please let me know if you have any other concerns.
