Just performed the Innuos 2.2.5 update, firstly the ripper no longer worked unless I use automatic and then worse the naim app now cannot see it as the Innuos on the naim app.
Turns out the its the Innuos software has reset everything so you have to go into the integrations section and select UPnP and choose the Native option.
Just wanted to help out nd save people time, I spent 30 min trying different combos, maybe it was just me. But hope that helps someone to save time and annoyance with the Naim app which essentially it isn’t. !!!
