The Windows Spotify app was just updated via Windows Store to v1.83.318.0. App restarted after update, and when it started up again, I could no longer drag and drop tracks into playlists, or drag and drop playlist tracks to re-order them. Clicking and draggin simply does nothing. I've shut down and restarted the app several times, but same behavior persists.
This was working fine literally 15 minutes ago as I was using Spotify to arrange playlists before I went to the Windows Store to update apps.
