I sold an item on eBay where the buyer selected Evri as the shipping option. I wasn’t able to use Evri, so I sent it via Royal Mail instead. The item has been delivered and the buyer confirmed they’ve received it, but I can’t find any way to manually add the Royal Mail tracking number — eBay only gives me the option to print an Evri label. The buyer also says they don’t see any option to confirm delivery. How can I resolve this so the order shows as completed correctly?
