When I log into my account, Etsy displays a red banner at the top of my screen saying one of my listings is missing a return policy, and wanting me to update it. When I click to update it wants me to select a policy to apply to the listing. That's all well and good but Etsy doesn't anywhere tell me WHAT listing it is. I have over 200 listings, and 2 different policies, and which one gets applied depends on the listing. I can't add a policy if I don't know which listing it is that needs one!
Go to listing page - lower right hand corner - Return & Exchange - it will tell you which listing it is.
