From the readme:
3) Sometimes, plugin output may not render properly in your campaigns generated from posts. This is usually because the plugin doesn't have access to information it needs until it is displaying its output on the screen for an end user. The best suggestion in this case is to learn which of your plugins are problematic (most are fine) and adapt accordingly. We'll look for ways to improve this in the future too.
Any tips to help expand on this in the current version?
And I'll encourage others... help fund this project too!
