Naim Uniti Nova not seeing UPnP server

I have iMac running OS X 10.15.4 on which I was previously running Asset UPnP server.
Have switched Asset UPnP off and downloaded trial version of Audionirvana Software - this has correctly picked up my iTunes Library (ALAC) and also registered my TIDAL Hifi account.
I can push to both below using Audionirvanna on iMac and iPhone app

  • Naim Uniti Nova firmware
  • Naim Muso Streamer version 1.8.0
    However would like to use Naim App for multi roon, But Naim app shows no UPnP servers for either device
    Connections are all hardwired Ethernet

Audirvana is not an UPnP server, it can just stream to UPnP capable devices (UPnP renderers).

If you need an UPnP server you need to look elsewhere.

Thanks for the quick response. OK Will continue to trial in Push mode
