I'm facing the same issue: When trying to play an album, it plays only one song. After that playback stops. I'm using a HTS 9221 as playback device.
Inside the myremote app / simply share the player restarts the song every 9 seconds while the song plays on my HTS.

I hope somebody can help us here. So far any of the apps (myremote / simply share / airstudio) behave the same - and are therefore completley useless.
HTS firmware and Apps are up to date.
