I may have had a moan some while back about this, so apologies. I now get a message from Apple when I am using one of my other iPads warning me about the use of my Apple ID account, simply because I have logged in using a different one of my machines. The message contains an utterly laughable attempt at geolocating the other me, and nowadays I always seem to be in central London! Presumably it’s actually the result of trying to geolocate the place where some of Andrews and Arnold’s servers or routers are parked. Geolocation is always such a horrible joke. Does it ever work for anyone?
I have even - as an experiment - tried adding geolocation info into the dns for my own boxes’ IPv4 addresses to try to give things a little help. Mind you, Apple might be using IPv6 not IPv4 at certain times.
