Issues with Apple Music app in macOS 26 on Mac Desktop

There are problems with the Apple Music app on the desktop running the new iOS26 operating system.

1. I have several Playlists arranged in Playlist Folders. When I open the app, all the folders are expanded. If I delete songs from a Playlist, all of the folders collapse. If I add songs to a playlist, all of the folders expand.

2. Choosing to show are hide the status bar doesn’t make any difference.

3. When I select more than one song, I can no longer see the total length of the songs.
