We've found a strange behavior of Ebay API when calling **ReviseFixedPriceItem**. If an item is added to an active promotional sale, when calling the revise method it is removed from the sale. It's a bit strange but we thought **SetPromotionalSaleListings** was a good workaround, calling it right after the revise. But if the promotional sale is active, the **SetPromotionalSaleListings** call result is a **21916235** error "The promotional sale is currently being edited by another process and cannot be modified." We think it's a sort of bug. Anyone else experienced the same?
