@verita84 i'm not saying you're wrong, but i can't find any example anywhere else of anybody talking about this :P wasn't able to see it in wireshark at all, even with WDP on. it might be a bug or some weird thing with your setup. i almost wonder if adguard could be overwriting the opt-out somehow, or if the opt-out works in the same way by just blocking the domains but adguard picks it up faster so it shows there first. i know that using adguard + brave shields people will see that adguard is still doing a lot because it will catch stuff before the browser implementation does.

what are you using to track this out of curiosity?
