Www domain keeps awaiting for external DNS

I have the following netlify app
jade-cajeta-b86a61.netlify.app](https://jade-cajeta-b86a61.netlify.app

Im trying to link it to my custom domain, pokerdatahub.com. I have already changed the hover name servers to include Netlify’s DNS,

But only the pokerdatahub.com is linked, but the www domain keeps awaiting for external DNS
