Orbi RBR20 Circle Blocks ALL Internet Traffic

I have a mesh Orbi RBR20 AC2200 router (Router Firmware Version V2.6.2.104), and have been using the built in Circle parental controls. A few months ago we started receiving intermittent issues with adult profiles getting "circled" (not allowed access) to perfectly fine websites (no questionable content). We would often refresh the page, and would then be allowed.

This last week, we lost all internet access on devices connected to the Orbi. The internet connection was active on both the modem, and the Orbi router (speed test), but no devices connected to the Orbi via ethernet or wifi had access to the internet. After a lot of investigation, I found that when I entirely disabled Circle parental controls on the Orbi, all connected devices could access the internet.

Has support for Circle on Netgear been dropped? Circle was the main reason I chose Netgear over another router.
