“Giving knowledge” part is excellent but “tech of app” really needs to be improved a lot – TED Review

While I’m just watching the video, it just stops and drops out of App and returns to my home screen strike three times at a video. And while downloading, only the completed ones stay, not in the progress do not show up again and need to start download from the start. That isn’t really convenient for me.
