Hreflang: Missing Alternate URLs

The "Hreflang: Missing Alternate URLs" warning happens when a page has a hreflang tag pointing to another version, but the alternate version doesn’t link back.

To fix it, ensure each page’s hreflang tags include links to all its alternate versions.

For example, if the French page points to the Spanish page, the Spanish page should also point back to the French page in its hreflang tags. Double-check all your pages to ensure the alternate versions are properly linked to avoid this issue.

I hope this is what you are trying to ask.
