YouTube Shorts is 5 years old! They're updating the Shorts experience:

• Clear Screen mode temporarily hides icons/text so you can just watch the video
• 2x playback speed available
• Mute more easily: tap screen to pause, tap mute icon
• :heart: replaces :+1:
• No more "dislike" button. Use the "Not interested" or "Don't recommend this channel" controls instead
