This means I have to use only itunes for proper playlist organization as I have many nested playlists.
Ahhh I wanted to move away from iTunes; only this feature is making me in it.

I think MediaMonkey only supports this for Android (only with MediaMonkey for Android).

Yes Sir the nested structure in mediamonkey is not syncing with iPhone x.
I used all the tagging and renaming in mediamonkey along with nested folders organization, but the sync with iPhone gives a flat playlist appearance. Have to use iTunes. Kindly advise

Do you mean that it respects the nested Playlist structure?

Love mediamonkey ,
I have to use iTunes for Playlists folder structure sync to iPhone. Is this feature not available in mediamonkey.
Thx
