Family Sharing is not ready for the Sparks family. I’ve spent way too much time trying to make this all work and this weekend I’m officially throwing in the towel on Family Sharing until it gets better.
There are just 3 iOS devices in the Blanc family: my iPhone, my wife’s iPhone, and my iPad. They’re signed in with the same Apple ID for the store, and with our own Apple ID for email and calendar. It works great… for now.
