Red play button does not play analysis

Hi,
My students are having an issue with their youtube sync on their Lenovo PCs. When pressing the red play button, it only plays the attached video, and not the analysis. They have to separately press the yellow play button if they want to hear their analysis, which leads to sync issues. Any clues?
FYI, it works fine in my Macbook Air. The red play button starts both the video and the analysis.
Sincerely,
Uri

Hi, we’re sorry for that. Could you tell us what browsers you are using when experiencing that issue?
