Just found YouTube ads, i haven’t changed any setting and everything is to default…
Exact URL of the website in question:
Did the issue present with default Shields settings? (yes/no)
Yes
Does the site function as expected when Shields are turned off?
Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
Does the site work as expected when using Chrome?
Brave version (check About Brave):
Brave is up to date
Try adding these custom filters:
www.youtube.com###masthead-ad
www.youtube.com##.style-scope.ytd-in-feed-ad-layout-renderer.sparkles-light-cta
www.youtube.com###main-container
www.youtube.com###root-container
Thank you! i will give it a try now, ive just done a reset in the browser too 
I did a reset and i’m still getting Ads… 
i will try your custom filters! Thanks again 
Similar problem here, opened up youtube about half an hour ago and I hear an ad (haven’t ever seen an ad with brave shields on before) but the video for it is black like the reply above mine.
It’s the usual war between the axes and the shields, my fellow Brave users.
I just though i would briong it to your attention
We imported changes from https://github.com/uBlockOrigin/uAssets/commit/5caa3f38d487e133eac48708a65fc99e8a5a8725
Does adding this (in brave://adblock, custom rules)
youtube.com,youtubekids.com,youtube-nocookie.com##+js(json-prune, playerResponse.adPlacements playerResponse.playerAds adPlacements playerAds, streamingData.adaptiveFormats.1)
youtube.com,youtubekids.com,youtube-nocookie.com##+js(json-prune, playerResponse.adPlacements playerResponse.playerAds adPlacements playerAds, playerResponse.streamingData.adaptiveFormats.1)
Though it may hit a youtube anti-advert bait
This ones did the magic!
Which one of those lines help?
hola a mi tambien me salen anuncios como puedo quitar y resetear el navegador mas encima tengo una prueba muy importante
AFter adding all of them, both on the “blackboard” and “custom filters”, I got around 60% of success. You have to praise Google devs for this assault to our shields. I bet a lot of us is looking for an AdBlock extension right now, but I know you guys will overcome this. I will not switch from Brave for just this.
Hay unos “custom filter” que debes agregar en brave://settings/shields, son
“www.youtube.com###masthead-ad
www.youtube.com##.style-scope.ytd-in-feed-ad-layout-renderer.sparkles-light-cta
www.youtube.com###main-container
www.youtube.com###root-container
youtube.com,youtubekids.com,youtube-nocookie.com##+js(json-prune, playerResponse.adPlacements playerResponse.playerAds adPlacements playerAds, streamingData.adaptiveFormats.1)
youtube.com,youtubekids.com,youtube-nocookie.com##+js(json-prune, playerResponse.adPlacements playerResponse.playerAds adPlacements playerAds, playerResponse.streamingData.adaptiveFormats.1)”
y luegos reseteas.
como reseteo el navegador no soy tan bueno en la tecnologia
Hola. A mi tambien me estan apareciendo anuncios, exactamente desde hace unos 15 minutos. Y ningun filtro publicado acá funciona, los anuncios salen igual.
Vengo usando bloqueadores desde hace mas de 10 años y jamas se me habia colado un solo anuncio. Increible 
.
EDIT: He encontrado una solucion, al menos temporal. Si tienen Tampermonkey o similares pueden instalarse este script: https://github.com/gsrhax/No-ADS-YouTube (obviamente, usenlo bajo su propia responsabilidad)
not working for me though?
Vas al menú, sales del navegador, y lo vuelves a abrir.
Me funciona ese truco el 60% de los casos. Quiero usar skill en vez de una extensión.
It works for me around 60% of videos. If anything else fails, I should try an extension until Brave devs have solved. I’m not gonna switch browser.
Now it’s doing it to me too.
Youtube changed something.
