I have a similar problem to 5503 landis. I have copied the code into WebPlux4 site properties and have created an HTLM snippet and placed it next to the website main title. I can see the code is on my website when I click on 'view page source'. But, my verification is still failing. I don't know what to try next and would be grateful for your advice.
