Question about expected ARC behavior with downloaded music…

[Saturn94]

According to this thread, ARC isn’t allowing playing of some downloaded albums when the phone is in Airplane Mode.

Why I don't understand ARC

Dears, where is my error? I configured the last version of Roon and ARC on my Iphone. I downloaded some albums. I can see the downloaded album with the symbol indicating that the album has been downloaded on my Iphone. I set “Airplan mode” to be sure that no connection is active. I choose the download album in ARC … But I cannot play id because ARC told me that I am in offline mode … BUT, it is not this the reason why ARC has been development? Where is my Error? Ciao Claudio
