New site not changing via Github connection

Hi, I’ve just purchased a domain and have linked it to my Netlify site.
I now have 3 domains listed on Netlify:
-the original noahcdev.netlify.app,
-my new noahcdev.com (primary domain)
-www.noahcdev.com (which redirects to noahcdev.com)

I have connected a Github repository to my site so I can update it easily. However, the content (a test html page) only shows up when I go to noahcdev.netlify.app, and I want it to show up on noahcdev.com. When I go to noahcdev.com, it only shows the default page + message of the website that I bought the domain from.

Anyone know why this is happening?

hey there, it may have taken some time for DNS changes to propagate and correctly associate your netlify site with your custom domain.

this is what i am seeing:

try accessing it again from an incognito window? that’ll force a reload not from cache and you should see the freshest version.
