I'm a PRO user and I've opened two tickets, #243584 and #247265. The first was opened a month ago on November 26th and has been ignored for weeks. The second was asking about the status of the first and it to has been ignored as well. Four days ago I sent a message via your contact form and there has been no response to that, either.
I'm not sure what's going on over there but I'd really appreciate some support.
The plugin will not post scheduled items. It's configured to do so every few hours for each network type and doesn't do anything. Similar to this post, also unanswered: http://wordpress.org/support/topic/pro-version-to-schedule-autopost-existing-posts-doesnt-works
