Order of Playlist

I have Music version 1.0.5.14

Whenever I make a playlist, I sometimes try to change the order of the playlist right after I make the playlist.

I click on one of the songs, highlight it, and move it up or down, to where I want it in the playlist.

I can do this with a few songs, one at a time.

This always worked in the past with this Music app.

This last time I made a new playlist, it did not work. I could not manually move the songs.

I know I can click on sort, and sort by title or artist etc. But I like to do it my way, in the

order I like.

I don't know why it does not work this time.
