Should I be able to change Sonos radio channel from Homewave ?

I have 6 different radio channel configured in my Sonos system, ?I configures Homewave on my iphone so I can see the audio selector on my phone, when I radio, I have a list of my channels that appears on my phone, if I select any choice, Homewave does not show the change and SONOS does not either, is this a problem with Homewave, a configuration problem or a WAD ?

I am on vera3 UI5
Sonos plugin version 1.2
lates IOS Homewave app

This got broken with the 1.2 version of the plugin apparently. The next release of HomeWave will fix this.
