Warning to all Brave Browser Users
Blocking variations.brave.com which is used for A/B testing could potentially break Brave’s functionalities. For me did Brave’s “forgetful browsing” feature broke which seems to be disabled by default if you block this domain.
But they’re the only ones blocking ads on YouTube for iOS 😞
You can add something like AltStore to an unjailbroken iPhone and sideload a YouTube app with adblock built in.
