Apple Music on IOS 12 and Android 16, don't let me add songs to collaborative playlists

So, I have an iPhone 5s on IOS 12.5.8 and Apple Music on My Android phone , and when I try to add a song to My playlist (that is collaborative) doesn't show up, and adding a song directly into the playlist doesn't work either.

Sorry for grammar errors btw I don't talk English natively....
