Orbi RBF40 and Circle 1st Gen (paid) issues

I’m using the above configuration trying to manage chrome books used by my kids for school, but the experience is frustrating. We moved the chrome books to Ethernet connections for more stability a month or so ago and it has made the circle tracking and feature uses sporradic at best. For example I’ve set one device to have no internet access from 3pm to 8:00pm (off time) and 8:00pm to 8:00am (bedtime). After seeing my child on it last evening I’ve tested it myself and it has full internet access during this period. I also notice long delays in updating history, it’s not uncommon to see no history since yesterday even at 2 or 3 in the afternoon and a whole day of usage.

Can anyone please suggest a solution?
