Cloudflare pages on subdomains not automatically set up in web analytics

domain: pepper.fyi I’ve hosted a site on Cloudflare pages, and by default, it has a pages.dev domain. I’ve added my own custom domain (and subdomain, boids-react.pepper.fyi), but in web analytics, only the pepper.fyi shows up in analytics. boids-react.pepper.fyi doesn’t show up. In the DNS entry list, there’s a CNAME entry that maps boids-react to boids-react.pages.dev, and it’s proxied. I’ve even added a JS snippet since CF tells me that it doesn’t belong to any hostnames under my account, but it still shows 0 views even if i accessed the site multiple times using the boids-react.pepper.fyi URL with different devices.
