With the recent release of macOS Catalina, Apple has made changes to how iTunes playlists are stored and organized by iTunes. These changes have caused iTunes playlists to no longer be included when creating a network share through the BluOS app.
Our development team is aware of this recent change made by Apple and are currently working to resolve this issue as soon as possible in a future update.
If you are currently running Windows or a macOS version previous to Catalina, simply sharing the "iTunes" folder from your computer will still allow you to access your iTunes playlists through the BluOS app.
