Paused devices still connecting and able to use the Internet fo hours on end

without a resolution offered in the thread:

Devices paused through the xfinity home interface are still connecting to the Internet for hours on end, making parental control factually impossible without a physical confrontation. This is a serious issue when dealing with defiant youngsters who are physically taller & stronger than the parent.
