As a person having shipping labels out of eBay to, started encountering "Tracking number added is already used by a different seller." eBay phone support tells they are not aware of any issue reported. But for me it starting to happen to often not allowing to add tracking to the item, becoming a big concern not allowing to work properly. Any possible resolution or report that can be done for this to the dev. team?
It could be relegated to canceled labels by other people or to old databases not cleaned up in time. But it's an absolute bug, cos labels are unique for this item.
