I'd used Airplay2 for Tidal on SoundTouch 20.
But now, I can't use my iOS device any more, and SoundTouch app still doesn't support Tidal.
Finally, I figured out this as using an Android app which is mconnect Player Lite. This app works simply without any complex tech setting.
I recommend you this one on Android until SoundTouch app supports Tidal.
