Hi Ernest. So we are still having no luck. We have asked our theme support and they say it should work if we put it into the child theme (our theme has both a parent and child theme), which we have done. I attempted to attach the functions php file that we have put the code in to maybe see if you could spot something obvious. But it did not let us submit.
We are not getting an error message when the code is in the child theme, it is just not working. Are you aware of any other functions that potentially supersede the code and stop it working?
Thanks again, we appreciate the help.
Kyle
