Poorly programmed and designed to look good rather than to work well. I keep clicking links and it hides 90% of the video. just shows this sliver of screen and then the video "about" text on an opaque background hiding the rest. Instagram has also started doing this thing where if it thinks you've been watching the same video for too long it starts nudging the next one up in the frame. **** off Instagram, I will decide when I'm done.
