There are many older playlists here, but fortunately I did figure out yesterday but it wasn’t easy.
As far as I remember, I had to create a new post, and uploaded the YT link into that post with the “add external media ” prompt, after then had to “add to media library”, and voilá….
I still didn’t really understand though, why they have changed the older, much more simpler method: “Media library/ Add new / upload from URL… ”
