Thank you again for your reply and trying to help me.
Some background information that might help. My husband and I have been android users forever. We gave our son an Apple phone when he Was 13. I have now converted to an Apple phone begrudgingly so that I can more monitor his phone usage. In order to create time limits on apps, for example.
So I am new to the iPhone since January 1 of this year.
Attempting to answer your first question, I would have accepted the invitation using his phone and I think the answer is yes to your question. Meaning that on my phone, I am the family organizer and when I go into settings, I see myself as the family organizer and I see my son listed under family. From my phone I can control his time limits on apps and I can see his daily and weekly cell phone usage. So I think the answer to your question is yes?
i’ve just googled what a VPN is. I just checked my settings and it says my VPN is not connected. My son is not home at the moment but I would be 99.9% sure his wouldn’t be connected. It’s nothing we know anything about. But I will check his when he gets home.
yes, my son has a passcode and Face ID enabled. last night when trying to set up the Apple Cash, when it would ask for the Face ID and I would fail it would then ask for the passcode which I know and I could enter.
no, he only has the one Apple ID and the same for me.(but like I said, I did have to correct his date of birth about four months ago.)
thanks again
