Issues with Rumble videos not showing in Wordpress

I embed Rumble videos in my Wordpress site. No issues, untill now. All browsers show and do play these embedded videos, except… the Brave Browser. Here I get a notice that ‘some extension’ prevents the video from loading and playing. Any idea what this is about?

Example site link? Rumble is classed as invideo advertising which was added to Easylist.
