Khan Academy / video problem
I am using khan academy for the last 5 months. It was all right when the videos were played directly from youtube. But from the last one week, the videos are not played on youtube. The videos are of HD quality. So I cannot change the quality of a video. Also, the pink play button remains even after the video is playing and the screen cannot be played in expanded view. Therefore it is a request for you to fix the problem since the videos are extremely useful for me.
Hoping for a quick service
ps-I have attested a screenshot of the problem below.
