Ok the issue was they way WP Super Cache was configured… These should be checked:
Don’t cache pages for known users. (Recommended)
Don’t cache pages with GET parameters. (?x=y at the end of a url)

The first one is important because you could make changes all day and not see a difference until the page’s cache expires.

That … and I did not once, not once!, read the question you asked correctly. I apologize!

The correct shortcode is [connections link=true']

You are all set now.
