Hello,
I use Bee to sync to Windows Phone, because I don't (and don't wish to) subscribe to any services like Pandora, Xbox Music, etc. I prefer to curate my own music, put it into my own big library, and make playlists for the selection I want on my Lumia.
Now, on Windows Phone 8, it worked great! I'd sync two playlists (as PLAs) onto my phone, and the playlists as well as the music in them ended up on my phone. Smooth an easy.
Unfortunately, with the update to WP8.1, it seems Microsoft shot down support for PLA files on Windows Phone, and now only supports WPL. Now, when I sync through Bee, all the correct music ends up on my phone, but the phone doesn't recognize any playlists, so I just have a library of everything I want on my device. This happens regardless of what music player I use.
I've heard the Bee can manually export WPLs, so for now I'll try syncing songs as I have, and manually copying the two playlist files, but it would be nice if a future update allowed me to directly sync WPL files.
Thanks
