Customizing Code beaver builder not working

  1. in Customizing ▸ Code, I added some code
  2. click preview
  3. click publish.
  4. visit the site and didn’t find the code
  5. checked all sites and code didn’t reflect.

I’m trying to add my google search console meta code but not reflecting and get “Verification unsuccessful”. So why is that it is not reflecting even if it is already published.
