When trying to relist an item through the API, we are getting these messages all of a sudden: You've provided an invalid shipping policy. You've provided an invalid return policy. You've provided an invalid payment policy. As far as I know, nothing has changed on our end. I'm guessing that perhaps something has changed on the eBay side of things, and maybe these inactive listings have some associated policies that are invalid now? No clue. Can anyone provide any guidance as to what might be causing this all of a sudden? Thanks!
