I’ve heard even Brave users are having problems too. Youtube is finding ways on an almost minute to minute basis to circumvent everything that is being thrown at them.
When they start to bother me about ads, I go with a separate browser that is not logged into YouTube and whose cache is cleared out after each session. The limit there is I can't submit a comment or thumbs-up a video. I usually go back to my logged in browser, ignore the message, and summit the comment and/or thumbs-up.
I use Brave. All I have to do is hit refresh.
