Instant Hotspots with Family Sharing.
I am looking into Apple's Family Sharing on iOS which was included in the iOS 8 update. To make Family Sharing work you will need to log in seperate iCloud Accounts. However, my son connects to my iPhone 6 Plus through iOS 8's "Instant Hotspot" feature. I do know that having the "Instant Hotspot" feature to work, we both are logged into the same iCloud Account. Therefore, our data is sometimes merged together but we have work a rounds such as using our own email accounts to cater for notes, reminders, calendar, etc. My question is, if my son is logged into HIS own iCloud account and I'm logged into MY own iCloud account, can he still detect my iPhone 6's Personal Hotspot like he does now (see picture). Or is the only way for him to connect with my iPhone is for him to go on my iPhone go in the personal hotspot setting and then connect?
iPhone 6 Plus, iOS 8.3
