When we go to change the royalty on a product, there’s the following message: “If your product has been published over 24 hours ago, we’ll process your royalty change starting on the 20th of every month.” Doesn’t this mean that if it’s a NEW product that’s just been published, we can change the royalty and it will take effect immediately?
However, when I do change the royalty on a brand new product right after posting, the new royalty does NOT take effect right away. So I think this is a technical issue.
