Apple TV "User" access
When I want to add a "User" to my Apple TV (in the Settings..., Users and Accounts..., Suggested Users...) the "Confirm <user> on this Apple TV" screen comes up and below that it says "This user's media, app data in iCloud, and Game Center accounts will be visible to other user's on this Apple TV."
I'm not sure exactly what that entails, and I don't know why their media and app data should be visible to other users. Does anyone have insight as to how much data is exposed?
