Shuffle not shuffling

[KMonk]

I'm selecting what I believe to be the shuffle option when playing a playlist in the Wiim home app but it's not doing any shuffling. Am I doing something wrong or misinterpreting what looks very much like a shuffle icon I'm selecting?
Correction!!! In fact a limited amount of actual shuffling takes place, but the "queue" appears exactly as the playlist.

What music service and content are you playing?

Edit: just read your update. Might be worth submitting a ticket to WiiM via the settings / feedback section in the app so they can investigate fixing this

Tidal. I'm playing mainly self-created playlists.
