If you use iOS devices for watching YouTube, look into side-loading uYou+, it’s basically an edited YouTube app that removes most of the ads. You can stream from your phone to the apple TV, too, also without ads. You don’t need a jailbroken phone or anything like that.
Which adblocker are you using on iOS?
This Is what I’ve been using.
Adguard
DNS or an app? How does it work?
It works in safari and you can block anything like ublock. Not dns. You could run dns on a server and run your iphone’s network through it as well.
