Hi...I have two Era 100's as rears...in the new app both are listed, however when I try surround audio tests the left rear doesn't provide sound. I've tried to remove surround, however I get an error. How can I control/check/modify the left Era...there are no options available. I'm on android, so a trueplay suggestion wouldn't help. On the previous version of the app there were control options of each speaker.
