stefano79roma on "[Plugin: Jetpack by WordPress.com] "publicize"doesn't work with scheduled posts"

Hi, I have a problem with the "publicize"function (both Facebook and Twitter). I saw that it works only with real time publishing posts, and not with scheduled posts. Having just read this forum, I tried to reconnect both twitter and facebook without results. I have, between the others, a plugin called "duplicate post".
Thanks a lot, greets
