Playlisty says it has finished but my playlist is missing (or partially missing)!

This is because when Playlisty creates your playlist(s) it creates them in the cloud and (usually) it takes a little while to sync back to your device. There’s nothing you or we can do to speed this up Рbe patient and your playlists should be there in a few minutes.

You can check they made it to the cloud by looking at the Apple Music web site, here: https://music.apple.com
