Swing Tempo not working

Hi Guys,
I recently bought the S60, and could not wait to play with it.
But after some tests I noticed that the swing tempo app is not working, the watch doesn`t detect any swing at all.
I tried also to do do some test shots, and it seems that watch also doesn`t recognize my shots...
Is there something i`m missing ? I tried to calibrate the watch, but no detection at all .
Regards,
Harry
