Moving from Mac to Sonictransporter

It’s on the network, and I can locate it via the web browser. I attached a 5TB Hard drive and the sonicorbiter sees that as well. However, I cannot see either the attached HD or the internal drive using Finder. Nor does ChronoSynch see these (as I would need to do this to perform backups). And it still does not see the networked devices. If I switch the core back to my Mac, there they are.

I assume I can use my Mac to manage the Soncitransporter, but I also closed it on the Mac and tried to “find it” using only the Roon app on my iPhone. For some reason, the app doesn’t see the Sonicorbiter at all.

So much for plug and play, alas.

Any suggestions are greatly appreciated.
