Hmmm... Not sure if I got this right
You don't need a separate feed from us to Twitter, if you already connected your Facebook to Twitter and all posts from your Facebook wall are also being pushed to your Twitter feed. So when you deactivated our feed to Twitter, do you still get our posts from Facebook to Twitter? Or did you deactivate Facebook & Twitter connection and now you get no posts on Twitter at all?
Actually, could you please post your Facebook and Twitter links here, so we'll take a look at types of updates that were published there in a recent days? Thanks!
