[Mattches]

If it is the issue of ads appearing/the ad-block detection message showing, we have just released a fix for that, as stated here:

Ad block not working anymore on youtube

Looks like we have a fix in for this: https://old.reddit.com/r/brave_browser/comments/1hinfh3/youtube_now_suddenly_blocks_me_for_using_brave/m31kcmw/ In brave://components force an update of Brave Ad Block Updater too Version: 1.0.9653 or better Then refresh Youtube.com tabs (important). Let me know if it helps Ensure no other adblocker extension is enabled.
