Youtube Cast is not working

[ShalokShalom]

Youtube Cast is not working for me:

I do have the media router option enabled.

Still, my Youtube windows do not show a cast button.

I replicated it in private mode, to rule out extensions as the culprint.

Current version, Linux.

I could solve this one:

After choosing “Stream” from this menu, it not only worked, but it made the button show up in Youtube`s toolbar below the video as well.
