Thanks, these are valid. Although the way the timings are displayed isn’t exactly intuitive that they are clickable, and it is a bit difficult to click on as the area is very tiny. I also noticed that these links embed my user information. I don’t want my user information embeded when I go to share a link, not sure if that can be changed though. but just a preference thing for sure.
Also agree heavily with pspeed that the header disappearing is a poor choice.
