Website domain stuck at verifying but subdomains working

I have a Pages project and I'm trying to add a domain to it. So the site has been added under Websites, but when I add this under Custom Domains in the Pages section it stays at verifying. It says 'Active' and 'data will be available here once available' I have another existing domain, which I can added as a subdomain for this pages and that verifies fine eg

Are you able to share the domain eithere here or in DMs?

turns out the client hadn't updated the nameservers or something on their side. In the end I think we just set up a redirect and parked the issue

Fair enough
