Embed a youtube video with ads

I have notice that when i embed a youtube video in a ibooks author widget the ads that supposed to be placed inside the video dont show! Is that normal behaviour ??? Is youtube restriction???Ior i have to to do smth my self…

Do you mean preroll or the text overlay ads? Feel free to share a video that you expect has ads and how you’re embedding it. (I have YouTube Red so sometimes it is hard for me to test youtube with ads!).

I’m not sure why there would be any difference; though it does appear there is an option to disable ads on embedded videos:
