I am unclear where to find the settings tab to which you refer.
When I attempt to start Roon, I get stuck with a spinning wheel looking for a “Core Device.” Consequently, I am unable to access a Roon app settings tab.
iPad settings does not show any Roon options.
Sorry for my inexperience. I am sure it’s any easy fix.
I wish to play around with Roon while at a second home. In our main system I have an Auralic Altair on which I hope to use Roon.
Your suspicions are correct… the Roon Core can not run on an iPad, the Roon app on the iPad is a Roon Remote / Roon Endpoint.
You need to have an Intel i3 or faster device for the Roon Core. Checkout the Roon Knowledge Base it’s a great reference source for new and experienced users alike.
