Maybe that's what it was. I usually stick to Safari when I can, and I used uBlock because it doesn't have uBlock origin. That blocked everything except video ads, which if they should have been skippable it could have been making them unskippable. I switched to Wipr that uses the content blocker API and that removes the video ads too.
