Hello,
Thank you for contacting Rank Math support.
The Rank Math SEO should be your excerpt by default – unless you’re using a theme that does not support it. You can test this by switching to a different theme, i.e. a WordPress default theme, to see if it works.
If you’re still having issues with this, please share your website access with us so we can help investigate the issue.
Thank you for your patience and cooperation
