I have sold some items and used my own on line Royal Mail account to send as Tracked 48.
I can't mark the items as dispatched as get stuck in the ebay postage loop. I've messaged the buyers to explain and that's all ok. Will this cause a problem with release of funds
If you've bought your own label to add the new tracking number and mark as dispatched you still need to generate the original prepaid label. Then go to the More Actions dropdown menu or View Order Details > Postage > Track Package > dropdown arrow and change the tracking. That has to be done on a desktop browser.
