A great plugin! works flawlessly for weeks, thanks.
However, I use automation posting, and when the auto post software creates the post, the alternate URL in the custom field provided do not show up in the Twitter shortened link.
If I go to that same post after, and click update the post, then the proper URL from the custom field gets sent to Twitter fine.
Is this a small bug? since I have not yet found a question about anybody using the custom field for alternate URL, found in the prefs section.
