Songs in playlist not visible on the phone app

[Chrmq]

Recently out of a premium plan, and now o cant see the content/songs in any of my playlist when I'm in the phone app. That includes the ones I myself have made. 

Does it have anything to do with it being the free version?

Is seeing songs in the playlist secretly a premium feature?

Can it be fixed? (Without spending hours making the playlists again)

Update: it's ALLol of the songs. None will come up. It constantly says that I "discovered a premium feature"

So assuming searching up songs are a free feature. What's wrong?
