Edit: Wait... Does everybody see this? It's not on all videos, but it's on most for me, but my girlfriend says she never noticed it. I can't find any articles claiming it was ever fully rolled out, so maybe it's a premium feature? Here's the vid if anybody wants to check:

I don’t see it on mobile unless I turn off my ad blocking extension. Thank you! Never knew that was there.

Great video btw, two musicians with great communication and flow
