Ubuntu 20.04 - no ads being blocked

Description of the issue:
As of today, ads are all coming through as though I’m using Chrome etc. without any ad-blocking. on the latest version of Brave and cant seem to replicate on my Windows PC. I noticed this on Youtube but have verified on other sites as well.

Exact URL of the website in question:
Here is a video but its not specific to any particular URL as far as i can see.

Screenshot of the ad as it appears in Brave

Did the issue present with default Shields settings? (yes/no)
Yes

Does the site function as expected when Shields are turned off?
yes

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
Not as far as Im aware

Does the site work as expected when using Chrome?
Yes

Brave version (check About Brave):
1.38.109

Ocassionaly happens:

  1. just ensure ads/trackers in shields is enabled.
  2. then Clear the cookies/cache in brave://settings/clearBrowserData
  3. restart the browser and relogin into youtube.

Thanks for the reply. Tried that a couple of times but it unfortunately hasnt helped

Does adding Fanboy Annoyances in brave://adblock help? also test in private window mode, with no extensions.

Still seeing ads in a private browser too. Adding the Annoyances list did seem to help though, so thank you!

Scratch that… Issue remains Im afraid
