Serial number of iPad not recognised by trade in tool
I have recently used the trade in tool to purchase an iPhone XR. It worked very well.
I am considering using it to trade in my iPad air for an newer version but the trade in tool does not recognise the serial number of my iPad. However Apple do recognise it when I check its warranty (or lack of it as it is now). Anyone had the same and got round it?
iPad Air, iOS 11
