@YouTube is there any word on why my watch later and downloads dont update or only show a few videos and say the rest cant be downloaded? I assume it's happening elsewhere as well
Are you trying to manage your Watch Later playlist? Here's how: https://yt.be/help/jpvQ . It will not be updated unless you've added/deleted videos or if the video has been deleted by the uploader. Also, not all videos are available for download. Hope that helps to clarify.
