I used Royal mail Click and Drop currently to send out our parcels. Its been connected to shopify which adds my orders into royal mail. I apply postage and then mark all orders as fulfilled, following paying and generating the labels. I then mark as despatched with royal mail. Royal mail is then meant to update the orders tracking numbers so I don't have to do it manually but It's currently not doing it?
Any ideas what I can do to make it work?
