Both (all) ads are bad though. I would rather have none of them while surfing the web. NextDNS and uBlock has been such a friend over the years for me regarding that 🥰
Didn't had any issue with it so far. Not sure what you're facing though. It just has some basic setup (nothing complicated). Maybe look to one of the step-by-step guide on the internet to find out where things are going wrong?
