Bear with me, as I'm a bit dim when it comes to technical matters. OK, here's the situation for a start. I've just signed up for the 3-month free trial of Apple Music, more specifically to the family account. For this account to work requires that other invited family members have an iCloud account. This is no problem where my wife is concerned, as she already has such an account. My two children, both over 13, do not. What is more, they have neither Macs nor iOS devices, and, as I understand it, iCloud accounts can only be created on such devices. (It's not a problem that they don't have them for our purposes of course, since they can use Apple Music through iTunes on their Windows PCs and Android phones.) The difficulty is this: how can I create an iCloud account for them? Can I do it on my iPhone or iPad, even though those are already connected to my own iCloud accounts? Once done (if it's possible), can I sign out of their newly created iCloud accounts on my device? Sorry if I'm being thick here!
