Issue resolved. There was a problem with a link to the .js. Once I used https URL, it started working.
Have you recently updated the plugin and since then the issue arises? What's the version of the plugin?
The plugin uses wp_head hook to insert codes. Others plugin and themes also usage the hook. The first script loaded is probably have high priority.

Let me know if you need clarification.
The last change was made on April 26th in WordPress SVN repository.
Have you cleared cache?
