Building your own UI using clerk & t3

Hello, Im currently trying to create a custom sign-up page and sign-in page following the Clerk Documentation https://clerk.com/docs/users/build-your-own-ui#theming-customization. I'm running into some troubles I was wondering if someone could help me out? I added all of the required files and updated my _app.tsx to reflect the example but whenever an unsigned in user hits my website it just redirects them to this page instead of a page looking like this. Any ideas what could be going wrong? 😩
