How to's : Philips Hue & AirManager

Hello there,

Now that Philips Hue is native, I still have a problem.
AirStudio imported my Hue lamps in my AirStudio file but when I try to trigger one of them from the app nothing happend.

Even the browsers recognize them but when I select a lamp and click « on » or « off » nothing happens (the dots blink for left to right then green but nothing happens)

Any clue ?

Thanks

Rudy
