Just registered for a MyVolumio trial and even wiped out an old Mac mini so I could install Volumio.
Then installed the Volumio app on both iPhone and iPad, being absolutely sure that I would be able to see my content AND play it on those devices through the network.
Alas, these apps or even the browser access are virtually useless, as no listening experience can be had. So why the heck do we install them? Just so I could remote control a computer that is already in front of me?
