Jetpack Facebook Publicize issues

Ever since upgrading to WordPress 3.8, the Facebook Publicize feature has stopped working. I’ve read numerous support requests about the same issue and none have worked.

I have disconnected/reconnected several times, disabled plugins (although nothing new has been installed that has affected it), tried everything recommended and nothing.

Can someone please suggest what to do next?
