Netlify forms submission cannot use custom success message in React

I deployed a React site with a form using a Cruip.com template. Everything on the site and the form is working fine, except I cannot get the form to use my custom action page and the default Netlify “thank you” message shows no matter what I do.

On form submission the form works, and the page appears to redirect to my custom action="/follow-up" page. It is visible in the URL bar, but the Netlify thank you message still appears. A simple refresh actually loads the page I want.

I have a /public folder with a _redirects file in there with /* /index.html 200 and the direct linking on the site is working fine.

Form is built and working with a simple action="/follow-up" and I can see on the site everything is working.

Decise - Technical Management Consultancy ← this is the form
Decise - Technical Management Consultancy ← this in the custom success message

Sorry if you’ve already been over the docs, but does your action param value start with a /, like so?

<form
  name="contact"
  action="/pages/success"
  method="POST"
  data-netlify="true"
></form>

Hi Phil, thanks for replying. I have read every doc under the sun and yes my action="/follow-up"

you can see the page live: deciseglobal.com/follow-up
