Raspberry Pi 1 B Tidal Connect Issue

I have 3 Raspberry Pi’s, all on version 3.198.
MyVolumio Premium enabled on all 3.

(2) Raspberry Pi 4’s that show up as Tidal Connect endpoints.

(1) Raspberry Pi 1 B where Tidal Connect is enabled and shows started in the UI, but it never shows up on any Tidal client as an available Tidal Connect target.

Unfortunately TIDAL Connect does not work on PI 1 (and PI Zero). There is no solution to that unfortunately…

Okay, 1 mystery solved at least.

Is that documented anywhere?
Why is it in the UI?

Although, to be fair, it doesn’t really work on the Pi 4, either. It plays a few songs and then stops. But, that’s another issue.
