@stephanie_moore ...
Ah! I see what you mean now. You are referring to the "Comments" setting once the Studio media is embedded on a content page...as described under the "View Comments" and "View Comment Timeline" headings of this Guide: How do I play a media file in Canvas Studio? - Instructure Community (canvaslms.com). The Guide indicates those are "inline" comments. I tried adding my own comments to a video in my Studio library and then embedding that video on a content page in my own sandbox course. However, those inline comments weren't showing up as I expected them to. (This is with the "Display Media Tabs" toggle switch turned off.) However, if I try re-embedding the video with the "Display Media Tabs" toggle turned on (green), then the "Comments" toggle you see in the "Settings" menu does have some visible functionality. If you keep the "Comments" toggle switch on, you will see dots above the playhead timeline of the video where someone has left a comment. But, if you toggle the "Comments" off, then you will not see that dot. So, with the "Comments" in the off position, you will not see those comments show up on top of the video. But, if you turn them on, you will see the comments on top of the video. The discussion interface (by enabling the "Display Media Tabs" toggle) will still show beneath the video...no matter if you have "Comments" turned on/off. And, you'll still be able to see exactly when those comments were posted...and by who.
I hope I didn't make this too confusing...and I hope it will help to explain how things currently work with those toggle switches.
