Looks like Dropbox isn't quite as simple as we would hope, based on other forum posts.
Right now, I'm experiencing an issue where files added to DropBox aren't showing up here an PA. I've added a file an hour ago and another one ten minutes ago. Neither has appeared in PA.
The opposite is not true, and is near-instataneous. Files added here in PA show up immediately in Dropbox.
Any ideas?
