Audirvana 3.5.3 does find my OPPO 103 UDP on my network

I recently download Audirvana 3.5 and wanted to play music through OPPO 103, but the app can’t find it on the my network. Audirvana 3.2 finds it plays music flawlessly. Why can’t V 3.5 do the same?

Hello @map1947, are you using the 3.2 and 3.5 at the same time while you are trying to connect to your OPPO?
