Good evening Luke and welcome back!
This is a great question.
This specific message is not part of our code. In fact, there is a ticket to make it part of our code.
Unfortunately, I cannot commit to a release date at this point. But stay tuned, you will be contacted when the feature is released.
So if you are seeing such a message, it means that there is some custom code in place on your site. I would suspect in your theme files.
Could you please send me a copy of the latest version of your WordPress theme / child theme via a link to a .zip file link (stored Dropbox or Google Drive) so that I can run some tests on my end ? I recommend a private reply for that purpose.
Please ensure you are using the latest files as found on your actual website.
This way I will get access to any updates or customizations you might have made.
Best regards,
Geoff B.
