Precise location or live location
i have the family sharing on with two of my daughters. One has a live location on anytime she goes anywhere. It literally follows her precise location as the other one it just gives a location, but not precise.
Question marked as
Precise location may be turned off. Try Settings > Privacy and Security > Location Services > Find My > Precise Location. If that doesn't work, disable Find My, turn it back on, then share the location through the Find My app.
