I’ve noticed this on my TV’s YouTube app as well. It went from 15 second I shippable ads, to 2 ads where I need to watch at least one and only then can I skip, to sometimes at least 30 seconds before I can skip. It’s worse on the longer video essays that I like watching, where they say “Fewer ad breaks for this long video”, but in reality they have the same amount of ads that you need to watch more of to skip. I absolutely fucking hate it :D
