I checked the problem and you are right.
I get an error when trying to connect from Android:
tidal_connect_application handle_transport_init received error: TLS handshake failed
This bug has been present since Tidal Music v2.65. For it to work, you need to uninstall the current version and install v2.64.2. (You also need to uncheck Enable TIDAL auto update in Google Play Store)
v2.64.2 can be installed from APK Mirror
https://www.apkmirror.com/apk/tidal/tidal-tidal/tidal-tidal-2-64-2-release/
I installed the nodpi version and it works (need to allow installation from this source)
The version of the firmware update + tidal connect that I prepared uses the project from GitHub and unfortunately there is no update for operation with an android app above 2.64.2
Maybe Gustard will try and make their version work, but when will it happen?
Edit:
And this is the link to the latest (unofficial) version with Tidal Connect support but with Roon Bridge disabled. The streamer then uses 50MB of RAM less and the total consumption when playing from Tidal is about 60% of RAM

@siwmad confirmed it works.
