Thanks for bringing the error message to our attention. We’ll look into that.
Good idea to separate safe search from Access Control. We’ll see how that can be accomplished. It’s not a simple modification of dnsmasq config. But overall, when Access Control is disabled, the router does not enforce anything, even for adblock. With Access Control disabled, DNS settings on the device override that on the router. But as long as router DNS is used, the settings on the router take effect.
