I have 255 YouTube playlists that are created by me. I've noticed that the ones that I updated the longest time ago don't show on the list of playlists when I click on "add to playlist" on a video. I've tried both on web browser and the YouTube Android app. Same result.
Just right now to do a test, I've seen that the playlist at the bottom of the list was "Football videos". Then I've created a new playlist "Basketball videos". Then I've refreshed the page and opened a new video. I've clicked on "add to playlist". The new playlist "Basketball videos" naturally shows at the top, but the old playlist "Football videos" isn't at the bottom anymore, and instead the bottom one is the one that was just above "Football videos" before. So there is indeed a hard limit on how many playlists show on the list.
My question is: What to do with this limitation? What's the point of being able to create an unlimited number of playlists if you can't add videos to the oldest ones past a certain number of playlists?
I know that you can open a playlist, no matter how old, click on "add videos", and add them manually from there. But that's clunky and I don't want to do it that way because when I add a video to a playlist I'm on the video's page. I don't want to go search for the playlist on another tab to add the video manually.
