Videos don’t play

Very frustrating. I can’t figure out how to play the videos. I tap a video, then tap play. It takes me to a blank screen with some ambient audio in the background, but no video or audio plays. If I tap the screen at this time, some kind of progress bar appears at the top of the screen, but it doesn’t do anything if I move it back and forth. Am I just doing something wrong here?
