Just the same problem again...
I use a Thecus N3200 pro with Twonky Media Server 4.4.11, a WDTV life and a Galaxy tab with Twonky Mobile.
I cannot find a way to play more than one MP3 song at a time. I do not think, that this is a problem of the WDTV live, because it works fine with the 2player app. Even when the screen is turned off.
Is there anything, making things work, in the next update of Twonky Mobile? If yes, when will the update be available?
