@TeamYouTube Remember what I mentioned before? About certain saved playlists not showing up on the saved playlists section even though I added them? It's still happening to me... and uninstalling YouTube and reinstalling it didn't work.
Sorry to hear you're still having issues. We'd recommend sending a feedback report directly from YouTube, here's how: https://yt.be/help/feedback . Make sure to send from the account experiencing the issue!
