Hi @Regan - hope you're keeping well!
The homepage, if you're looking to setup exclusions, would be denoted by a slash, ' / ' , as a single page entry (do not use directory, this will disable ads for your whole site. You must use single page with the / as the URL input).
Regarding seeing ads on the wp-admin pages, Ezoic automatically excludes the admin - the only time this is possible is if your site is not using the standard *.com/wp-admin URL pattern, i.e. if you're using a plugin to change the login URL.
If that's the case, we'd most likely need to setup an alternative solution for stopping the ads.
The other thing we'd like you to check is that they are in fact coming from Ezoic. Can you right click on the ad in the admin, and click 'inspect' - then send us a screenshot of the Ezoic placeholder code showing.
