Has anyone had an issue with the simple delivery postage labels printed from the ebay site, not being accepted at UK post offices? I dispatched 3 items using these labels and all 3 were rejected at the post office. The reason given was that the QR code & tracking provided contradicted each other as one was for 'Standard Delivery' and the other was for Tracked 48. So the post office computer system would not recognise or process the dispatch of the items. I was also told by post office staff this had happened with several other ebay sellers
