From any device (iPhone, iPad and Mac), when I go into Settings -> Setup and click Configure, I get a dialog that says “Searching for devices…” that never returns.
Is that the “Configure Roon OS Devices”?
You have Roon running on Mac so I suspect you don’t have a Nucleus or any ROCK devices on your network. Hence it can’t find any, just click on “done” to exit.
Sorry, my bad- I see it says “Roon OS devices”. I removed a device accidentally, which is a raspberry pi running Ropieee that I use for album art display. I went there to add it again but it is actually under the “Audio” tab and I needed to click “Enable”. Been a while since I set everything up and forgot where to go
