In case you need to print again a label with new shipping information you don't have to move the order back to To Ship section.
In fact, what you can do is actually much easier than that! ✨
To update shipment info you can click on the pencil icon on the right of the order and then add there the new data. Once done, just confirm and a new label containing the updated info will be generated automatically.
If you need to change Carrier employed instead, make sure that your marketplace doesn't present the green tick ✅over it, then click on the blue arrow Icon on the right of the order.
It will move the order back to To Ship section and you'll be able to ship it again with a new service.
Done! 🎉
