Daughter getting iPhone Messages I send my wife on iPhone
I know this has be discussed before, but all of the searches I've made via Google show older results that don't reflect the latest 10.2.1 iOS Settings layouts.
We recently got my daughter a new iPad and put her on our family iCloud plan. I now get photos from her iPad on my iMac at home, and she gets the Messages my wife and I send back and forth on our iPhones.
How do I eliminate this privacy breach? Just now on MY iPhone, I've got to Settings > Messages and turned off iMessage. What more do I need to do to keep our personal conversations private?
Thanks!
