Firstly, you can see what version you have at the Moode menu (at top right) > Configure > System > Moode menu (again) > System Info. If it's not 6.4.2 it not current and as Tim said you should update before expecting support.

3. Hit the EDIT button for UPnP config and enter/save your Tidal credentials
In BubbleUPnP mobile app...
1. In BubbleUPnP's settings goto 'Local and Cloud' > 'TIDAL' and enter your Tidal creds, exit settings.
2. Select the 'Local and cloud' library, navigate to Tidal. You should be able to navigate & play your Tidal library in BubbleUPnP on your mobile device.
3. Hit the renderer button (looks like a Chromecast icon), if you're on the same LAN as your Pi you should see Moode UPnP as an available renderer, select that to output from Moode
