Playlists not syncing between iPad and iPhone

I’ve recently downloaded Djay using the same Apple ID on both my iPad and iPhone. I’ve set up a playlist on the iPad but no songs or playlists appear on my iPhone when I wanted to edit it later?

Let’s hope this will be solved with iOS 13 and/or iPadOS
We definitely need FULL sync between iOS devices


This is on our agenda.
