I find that videos in the community lag a lot and cannot play smoothly. For example, the videos under "Wisdom for learning English” and “Fix your pronunciation".
However, there is a "resources" option under "PIRF FRESH 25 Speaking lessons". When I click Download, it jumps to a webpage asking if I want to download. After I click the button shown, the videos on this page play very smoothly without lagging.
Has anyone encountered the same issue as me? I don't know how to fix this problem.
