‘Threat found’ displays but nothing reported

Hi,

‘Threat found’ is displaying in the WordPress menu bar, but when you follow that link (which goes to https://jetpack.com/redirect/?source=calypso-scanner&site=sitenameremoved) it just displays a page saying “Uh oh. Page not found. Sorry, the page you were looking for doesn’t exist or has been moved.”! This is on a free plan.
