featured image doesn't appear in social media preview

Hi everyone,

I'm loving this fantastic theme! It's definitely one of the best I've come across.
There's just one minor issue preventing it from being perfect. When I share a link on Facebook or LinkedIn, the featured image doesn't appear in the preview.
Does anyone know how to fix this?

Thanks,

Use this:

cover:
    image: "cover.png"
    alt: "your alt"
    relative: true # Must be explicitly set in the front matter to work correctly

And build Hugo in production mode (not via hugo server). Although looks like you've already solved that :)
