I am unable to get Roon to link on my iPad.
Ideallly I would like Roon to play on my Auralic Aries Mini which is on the same Wi-fi network but I can’t get this to work. Would bit be better to connect the Aries Mini by ethernet rather than Wi-fi?
I am then connecting my Aries Mini to a pair Of Devialet Gold Phantoms (plus Dialogue) by Optical Toslink connection.
Please can you advise

Hi @Peter_Hill,

Are other remotes experiencing the same issue, or just the iPad?

Was this working before the update to Catalina?
