That's been a thing for years now like back before I got premium which was at least 4 years ago the skip button would skip the first ad and then bring you into a timed ad afterward that you couldn't skip, was obnoxious as hell
it's improved for me, as someone who easily watches 20ish hours of video a week It's worth it for me to not have to deal with all the hassle of ad block on it. I run a pihole for everything else but the cat and mouse game got old. I currently get my money's worth, but if it raises much further I'll cancel.
