Yesterday I experienced something I never saw before: My iPhone is on iOS 13. My family is still on 12.4. My wife and I are defined as parents / guardians in iCloud family. We all share location between ourselves. What I saw yesterday is that my phone gave me a notification when my son set an alert for when my location changes. In other words, he used Find my Friends on iOS 12 to get a notification when I leave my current location (he wanted to bug me to stop by a store and get ice cream, as it turns out.) What struck me as odd is that I never got this notification before. Is this new? Will in iOS 13 all people get a notification that someone has set up a location-based alert on them, or is it just because I'm a parent? Or was this always there?
