Thanks so much for the prompt reply @hillary .
I followed the sites and links that you posted above, but I’m still stuck.
I’ve actually added a custom domain to two other sites that I created recently (one on my own Netlify account and one on my daughter’s Netlify account), so I’m familiar with the process and have done this successfully before. I’m following the same steps that I’ve followed before, so I’m confused as to why those steps are now failing to work.
To retrace my steps:
I click the Add custom domain button in the Site settings for the site:
On the next screen, I enter in the URL and click the Yes, add domain option.
I’m presented with an error message: custom_domain is owned by another account.
Let me know what my next steps should be or if I should be doing additional changes (e.g. adding DNS records through my domain registrar) to allow me to add a custom domain to my site.
