Parental Controls on C7800 DO NOT WORK - DO NOT BUY THIS CABLE MODEM!!!

I cannot believe I purchased a $300 top of the line cable modem router branded NIghthawk from a company Netgear known to make great products only to find out it is not supported by the Nighthawk App. Why brand it Nighthawk if it is not truly a member of the Nighthawk brand family? How can Xfinity's cable modem router gateway have an app that works great and yours does not. Why does having a cable modem in the same product make it some unsurmountable technical feat to have it compatible with the Nighthawk App. Now I have returned my Xfinity gateway to avoid $14/ month fee and lost my piece of mind and ability to control my childrens devices access to the internet. I was so excited to upgrade our network and now am just upset everyday. Please fix this situation! This is a terrible oversight on your part. You need to think from the customer experience forward and I am having a terrible customer experience. My assumption is that you are focused solely on your Orbi brand family and this Netgear product fell through the cracks. That is unacceptable. If you don't have the bandwith to fully support a product don't release it, discontinue it.
