How to redirect one page from subdomain to another subdomain

I want to redirect one page from one of my subdomains, to another subdomain. How do I achieve that?

More specifically, I want to achieve:

folks follow link… https://www.theuap.com/ultimate-frisbee-workout-guide
and end up at … https://pages.theuap.com/ultimate-frisbee-workout-guide

I’ve setup a forwarding rule, and made it first…

But nothing happens. Folks who go to it get directed to the old page. (I know the new page works, because I’m able to redirect https://theuap.com/ultimate-frisbee-workout-guide to it. But I need to redirect from both the naked domain and the www subdomain).

Here’s my DNS for the www domain, showing it is proxied through Cloudflare so Page Rules should, I believe be kicking in…

What should I check next?
