It seems Parental Controls is not working when the client uses a VPN.
I defined an empty white list for time after 21:00 for my kid's mobile.
It works for regular browsing, but when they use a VPN to watch videos, it does not work.
Access Control works for that case, but it does not have a time-range ability, so I need to turn it on and off manually.
Please fix this issue for Parental Control.
