The timed comments feature started appearing to more users recently. It allows you to leave a comment on a particular time range of the video and participate in conversation with others.
Also, if you are lucky to get this feature early, it will only appear on some videos and not on all of them.
The timed comments feature is also labelled as Beta and hopefully will become available to everyone at some point. You can check the difference between the old and new versions on in-app screenshots above.
How to test:
- Open this video on YouTube >
- Tap on the comments section to open the comments view.
- Tap on the Settings icon below the video.
- Tap on the Timed Comments option.
Have you got Timed Comments as well?
