I have a YouTube App. One of the sections is "To Watch Later". Once I have a video in there, I can watch it at my convenience. Sometimes I delete it when I have seen it, sometimes, I leave it to watch over and over. UNFORTUNATELY, sometimes the video is removed by the Uploader or Administration for one reason or another. ALSO unfortunately, the Tab that allows me to select "Remove from 'Watch Later' " is disabled. How can I remove the unwatchable videos from there, so that more videos can be readily available?
