We don't use Canvas Studio, I know it's supposed to work if you import it in there (and it recently broke) but not asking about that here.
I did a test, and a video played ads on YouTube, but when just pasting a link in a Canvas page and opening it from there, there were no ads when I played the video.
Similarly, if I clicked the auto-embed Canvas puts in for YouTube videos, it did not play ads.
Further, even if I copied the embed code from the Share menu on YouTube, and put that in the embed thing in Canvas, then played that, there were no ads.
But, I can't tell if that's a coincidence or by-design? Like can we rely on that to be true always?
We also have a video host product, YuJa, that appeared to also remove ads but I have to also ask them if that's by-design.
Thanks for any insights 🙂
