I did hear the news about youtube getting rid of adblocks. The first video that I click has an ad and then I refresh again the ads still appear. I turn off and on ublock origin just to make sure it’s working and it blocks the youtube ads. It happened to my dissable youtube shorts plugins as well. Btw I am using firefox.
Haven’t had such issues on ether of my 2 machines. Chech in ublock settings that your rules are up to date.
Cold be that you are one if people they are testing something new on. Tnen it may not help you though.
