Please can somebody help. I’m trying to fill in the details to register for 5 year warranty. Can fill in all fields except for location of purchase. It needs to recognise the shop (in my case Currys) but it can’t find this retailer, it only finds 12 retailers all starting with A. I can’t get any further.

What’s going on ? I’m using 2020 iPad latest with latest update also tried to register via iPhone same issue.
