For workarounds -
Issue replaying videos on UiPath Academy Academy
I found another workaround, as it also doesn’t work for me on Firefox nor Chrome. (what doesn’t work seems to be navigating through the video via clicks on the progress bar). On Firefox, you can use this workaround: Load the page with the video Left click the video once Press Left arrow on your keyboard until you reach the beginning of the video. You can now watch it.
