Good Evening @Seller_OdE6ifaXNk7qV,

Please contact customer support for Printful to see if they are able to support and troubleshoot this message for your account. I cannot provide any further guidance as I support the Amazon Seller Forums side of this situation so I don't have insights into the Printful program or how setup works. Thank you for understanding and have a great weekend.

Sincerely, Cooper_Amazon
