Today all of my embedded YT videos in my OneNote book disappeared all of the sudden. They had been working but suddenly are not. The OneNote is within a Teams group and when I view the videos there only placeholders show- no videos. When I view the videos in the OneNote app and try to play them and error message pops up and tells me the video doesn't exist, which it does in YT. The links have not changed or been altered. Any help is appreciated. Our IST cannot figure it out.
