Problem with HEOS app and MinimServer

[noworries]

All,
I cannot get HEOS working at all.
I can browse to the Server and get the correct initial directory.
However, when I, for example, navigate to a playlist, I can see songs in some, and others end up in a recursive loop where I continuously have to select the same Playlist, but no songs ever appear.
It doesn't seem there's any logic to which playlists appear correctly and which don't.

Further, I am struggling to get media playing consistently altogether.
If I do get a list of songs in a directory or playlists, it's 50/50 whether it will start playing, and it NEVER continues to the next song automatically.
If a song is currently playing, and I select another song - well that freezes everything and I cannot get anything after that, short of rebooting the HEOS app, etc.

Any help appreciate.
