I've added a custom domain, and it's published. However, the default domain still appears in the SEO settings, and when searching for the main domain on Google, it doesn't display correctly.
Can you help me?

I am experiencing difficulty in connecting my custom domain to Webstudio. My hosting provider, Aruba, informed me that the CNAME host field cannot be left empty (i.e., using "@") as suggested in your instructions. Due to this, I am unable to complete the domain connection. Could you please assist me in resolving this issue and provide the correct configuration for linking the custom domain to Webstudio?
