Tidal playlist anomaly

I have downloaded a trial for a Mac and I am mightily impressed, I am running it through Volumio on a Pi, sound quality is great so will be buying license when my trial is over. However I have noticed an anomaly, on the Mac version I click on Tidal , then playlists and it shows all Tidal available lists, but on the app on my iPhone when I do that it shows me the playlists I have added to my account, which is what I would expect to get ! Any ideas ?
