Unhandled case where "resolver" is not present.

Greetings,

I have just purchased an annual NextDNS subscription to use at work as well as home.

I am using macOS Big Sur 11.2.3 on MacBook Air M1. I added the configuration profile, restarted the system, NextDNS is enabled with a special configuration ID, my IP is linked, but I am getting this error in the topic on my setup tab in safari.

When I refresh the page it says I'm not using NextDNS, then it changes to this error;

Error - Unhandled case where "resolver" is not present.

How do I resolve this error? Help would be greatly appreciated. Thank you.
