Analytics does not update when changes are made to settings after exceeding 300,000 queries

After passing the 300,000 limit, Nextdns stops filtering and turns into a normal secure DNS server. So that's why re-writes etc wouldn't work since you passed the limit. The logs not being updated I'm not sure of and lastly for the Analytics AI-Threat detection or any other filters that get involved very little won't show up if you have many filters enabled in the Privacy section. The top 6 Filters will be shown so if it's doing less blocking then your top 6 filters it won't show in your analytics.
