It used to work correctly, and pretty good in execution. You would tap the screen and a preview loop played while NOT opening the video video.

Now the video opens immediately with a light, hard, or medium tap. The preview function is gone. Good luck trying to scroll and no to open a video, it’s impossible without far too much. The correct amount of effort would be none.

The only reason I visit this site is because it’s one of four with tap to preview that works on iPhone or iPad. There is no reason to return now that it has been removed.
