Hi @Emil_Worndle,
Noris brought this issue to my attention and I wanted to reach out to see if you have received any more information from Naim on this issue.
As Noris mentioned in his post above, the fact that this device is disappearing more broadly (not just in Roon) is a key point here. If it was only Roon we might be able to resolve this, but unfortunately it looks like this issue goes beyond just Roon. If this issue is resolved the device should work appropriately with Roon.
We’re happy to help however we can, but ultimately some additional feedback from Naim on how to resolve the broader issue of the device disappearing is needed to resolve this.
