I have an iTunes Store account which has all my purchases over about ten years. For reasons we won’t go into, this isn’t my iCloud/Apple ID account I use for everything else at Apple. So I have signed into iCloud with my @me account on all my devices, but I always have this separate account signed in to App Store, iTunes Store, and Apple Music.
I want to be able to activate Family Sharing on the former account, so my family can view my purchases. I can’t seem to find a way to start this process from anywhere other than the iCloud menu.
Is there a way I can set up Family Sharing without signing into/using iCloud?
