A key feature of Apple's iCloud Family Sharing is the ability to share store purchases with invited family members. However, like many people, I use a different Apple ID for iCloud and Store purchases (ironically, primarily for the exact purpose of sharing among family).
Can I use iCloud Family Sharing to share purchases if I use a different Apple ID for Store (iTunes, App Store, etc.) purchases? I understand that if I send invitations from the ID I use for purchases, I can share them; but there seems to be no way to do this, given that I use a different ID for iCloud on all my devices.
