It was brought to my attention a while ago, but why does @YouTube not have a "watch next" feature on their own platform? Unless I'm casting to a device I have to manage a new playlist to watch my videos?
Thanks for reaching out. "Up next" videos are located below the video player when using mobile or at the right side if you're using a desktop browser. If what you're referring to is "autoplay," you can check here to activate it: https://yt.be/help/8NfN
