I received a prompt on my iPhone to approve an app for my daughter today. When I went to Screen Time in settings, family members are no longer listed:
If I click Set Up Screen Time for Family, I get a prompt that I already have the max number of users set up (that is accurate).
If I look on my iPad, the family users show as expected. I did a force restart on iPhone but it did not fix the issue.
I also tried clicking Family on the main Settings page and drilling down to Screen Time there. It shows up under each member but says last updated 10/3 and will never refresh.
