Quickly Access Full-Screen Mode
By now, you probably already know that you can tap the full-screen button in the bottom right corner of a video to go to full-screen.
However, there’s a quicker and easier way to do it. All you need to do is put your finger on the video and swipe up. Whether you’re on the iPhone or iPad app, the video will automatically go to full-screen.
Likewise, if you swipe down on the video, you’ll go back to the regular mode.
