How to copy YouTube playlist URL

Liking a playlist will add it to the playlists section in the vertical menu bar on the left

I just found out another alternative for grabbing someones playlist by accident (though the playlist appears in your channel, you dont actually copy their playlist to your own collection of playlists).

I was trying to delete playlists on the desktop, but I noticed some extra playlists there were appearing in my tablet. These playlists were in the vertical menu bar on the left, and I couldnt delete these particular playlists.

Going back on the desktop, I didnt see these playlists when I clicked on playlists on the top, which is to the right of your name.

I found out that they werent actually my playlists. I initially didnt know why someone elses playlist were showing up in my list of playlists, but then I noticed that I had liked their playlist.

Liking a playlist will add it to the playlists section in the vertical menu bar on the left (not the top). I suppose that the playlists on the left are your playlists, as well as other people's playlists that you have liked.
