We have had an issue when dispatching items within France with Tracking. "La Poste" is pre populated as our sender and after entering the tracking number Etsy responds with " This is not a Valid FedEx Number" . What's FedEx got to do with "La Poste" I ask myself?
The answer we have found is by entering "other" in the sender field and manually entering"la Poste" in a sub field then the tracking number and depatching works. So in summary if you are a supplier in France and dispatch internally within France you need to use the "other" field instead of the pre populated field. Could Etsy please look at this anomaly ?
