Thank you for the response, wp_footer(); is definitely being called. As I stated earlier, I already tried disabling all plugins besides the flipbook and still had no luck. For the sake of trying to resolve this, I have disabled the additional caching plugin being used, WP Rocket. The site is hosted on WP Engine and they provide their own caching as MU plugins, and I am unable to remove those. I was able to successfully load the js files manually by placing them in the theme and register/enqueueing them from functions.php. This did not resolve the issue and is not the answer. Any further suggestions/solutions would be greatly appreciated.
