Anyone having trouble getting Cloudflare Access to show on protected zones?

Been looking over settings again and again trying to make sure that I’m not missing something or going crazy.

Have one app (a WP backend login) secured through CF Access but - no matter what I change - the page won’t show.

Domain is:

→ Proxied through CF

→ Has Access configured through Zero Trust

Etc

(But it’s a free account so no paid support).

Anyone else experiencing something like this?

Do you receive an error message of some type?
