Interesting, I have yet to see any ads on my Roku Ultra ... that said, I haven't used it lately.Turned the Roku 4K streaming stick on that is on my patio tv to be greeted with an auto playing ad. Of course cursor wasn't on the close ad button either. So had to fumble to see where it was and move it to close the ad.
Guess I'll be ordering a couple more Apple TV 4k's. I refuse to put up with ads of any type.
