Pretty bad on my Roku. It really discourages you from watching more than a few videos. If I start a 10 min video and it wants to play 1 min of ads first I just go Back and hot play again, usually the ad length will get shorter. Usually have to do that 2 or 3 times to get to an ad I can skip after 5 or 10 seconds.
It’s too bad because Roku is good for everything else, fast UI and nice clean remote.
I kinda get it, if you want takeout food and you can’t or won’t drive it could be convenient. But it’s just so expensive.
