Hi, Chris, thanks for responding.
In my phone, under my child's section in the Screen Time setting, under "Content & Privacy Restrictions," I have set "Account Changes" to "Allow". In addition to screen time, I do have restrictions enabled on their phone (through the "Content & Privacy Restrictions" area on my phone for my child) re: app purchases, and music, TV shows, etc. Are you saying I need to take all those Content & Privacy Restrictions off? The "Share my Location" in the Content & Privacy Restrictions setting is set to allow. As is "Account Changes," as mentioned.
In my child's phone, as I've said, if I try to click on their profile under Settings, I cannot do anything.
If, on their phone, I go to "Location Services" under Privacy, it is set to On. If, on their phone, I go to "Find My," and then I click on "People" (which is where, on my phone, my family members are listed), it says that the profile is not signed in, and that we need to go to settings to sign in. But then it brings me back to the profile on Settings where I cannot sign in, where it is greyed out.
It would also appear that on my own phone, I am no longer able to change/control the screen time on my child's phone. (They still have screen time limits on their phone, because they do not know the password to change this, but I can no longer change these limits, or change the screen time password, on their phone from my phone).
All of this happened after we both installed the latest software update.
Please help!
