Cox Wifi app (Parental Controls)

I have been using the app for over a year with no issues.  The Parental Controls option is activated for both of my kids.  Last week the app began to completely block the devices assigned to each child.  If I deactivate the Parental Control option for each child, their devices work. I already rebooted my gateway, signed out and reloaded the app.  Nothing helps. Can some please provide some insight on what can be happening?
