How to update Facebook status through the Facebook PowerShell module? -

i'm using facebook powershell module connect facebook using powershell.

new-fbconnection logs me in successfully. get-fbconnection fetches results successfully. when try update status with

new-fbfeed -message "this test message."

i error "error in new-fb feed: (oauthexception - #200) (#200) user hasn't authorised application perform action"

i checked facebook apps setting, see owner app there. presume app has been authorised when first establish connection new-fbconnection. why unable post status update? thanks.
