Each member of our family has two unique Apple ID's, one for use with iTunes and another for iCloud (e.g. 4 members, 8 Apple ID's). On the family sharing page it says "Family Sharing requires a personal Apple ID signed in to iCloud and iTunes". We are hoping to achieve not only the shared apps functionality of 'family sharing' but also the shared calendar, photos and Apple music subscription.
Does this mean that each of us has to use the Apple ID's for our personal iCloud accounts to signin to itunes if we want to use 'family sharing'? i.e. we have to use the same Apple ID for iTunes and iCloud?
