I recently purchased a Samsung 5 44mm watch.

I've been using the Samsung Wear app to transfer music on my phone to the watch. 

Manage Content > Tracks on Watch > Playlists

I then create a playlist and upload a folder of songs (with 200-300 tracks per folder). I am having the following problems

1. I can see the Playlist title on my phone but cannot see any of the tracks within that playlist on my phone. On my watch however, they do appear

2. I tried deleting an playlist from my phone. The playlist disappeared from my watch but not from the phone.  This also happens with songs - video attached

How do I resolve these issues?

Thanks
