There are a few ways to share youtube videos on Xbox One. You can either share the video directly to your xbox one’s media player, or use the Xbox One’s Upload app to upload the video and then share it with others. To share a youtube video on Xbox One, first open the Upload app and select the video you want to share. Then click on the “Share” button and enter your desired information. For example, you could name the video “My First Day at School.” Once you’ve shared the video, it will be available for anyone to watch.
