When I open the tutorials and have them load on YouTube itself in a new tab, YouTube just sits there and refreshes itself. I see the page load briefly, but then it's gone again because YouTube keeps refreshing. This happened when I clicked several YouTube links from within a Google Document (Introduction to CODAP Guide), it happened when I clicked the link below the tutorial vidoes on the tutorial page, and it happened when I copied the link and opened up a new window and tried to watch it there.
As long as I don't try to watch the videos in YouTube and stay on the tutorial page, it will let me watch them. But I can't get any of them to stop refreshing when I click the links and go to the YouTube page itself. I'm wondering if there's an issue because it's trying to play an unlisted video from a link in a playlist? I have no idea. But it's definitely off-putting. I don't mind navigating back to tutorials every time I want to watch a video, but I thought someone should be aware.
FYI: I'm on Chrome Version 83.0.4103.97 (Official Build) (64-bit), Windows 10.
