It's not (yet) supported, so for now remove the Playlist from the sync selection for a successful sync.

Hi,

I recently added some radio streaming links to a playlist and it works fine on the pc.
When I try to sync with MM pro however, the sync does always stop and then start there forever trying to sync those links until I force close the app.

Given that not all radios are available on the streaming services that are in the radio tab would be great if it worked and at least didn't basically make syncing impossible. Any ideas?
