Hello,
i have the remote app on google pixel 2, android 10, audirvana 3.5.3 on mac os catalina
After my drive connection finally works, I don’t use the remote app. All devices use the same network and can be found among each other. The only app that can’t handle this is audirvana.
And unfortunately i have too much duplicate in my library …
I have no further idea what I could do 
What a pity, at this price
Cheers
