YouTube video unavailable

My YouTube video at https://youtu.be/lkRlCLF0wBE shows up as “video unavailable” when I try to play it in a portable Prezi, in either Prezi Classic or Prezi Next. That video plays fine in Present mode in either Prezi Classic or Prezi Next. Can anyone tell me what I have to do differently to get it to work in a portable Prezi.

A different YouTube video, at https://youtu.be/1YCx-GY1Cvo, does seem to work in a portable Prezi. I’d like to know why it works but the one I mentioned earlier doesn’t!
