Screen time is messed up to me.
On beta 4 my wife suddenly disappeared from family under screen time, and only my daughter was left. Under iCloud settings and iTunes,my wife is there.
I removed here from family and added here again, but she still don’t show up in screen time.
This was not a problem in beta 1,2 and 3.
Also, no data is showing on my daughter.
I think the fact that non-children family members aren't showing up in Screen Time is a feature, not a bug.
