I would like to run ads to my Merch shirts using AMS I tried everything to get approved nothing worked.
Thank you for the question. There isn't currently an option to create sponsored products through the Merch by Amazon portal, though if you already have an Amazon Marketing Services account you may be able to advertise them there. We know that the current experience with advertising Merch by Amazon products isn't ideal as we don't currently have integration with AMS. We are working on a solution, so if you don't already have an AMS account please stay tuned. We will make any announcements here on the forums as well as in the announcement section of the Merch by Amazon dashboard.
