Https://scan.nextcloud.com shows always "Latest patch level"

My Nextcloud is on version 19.0.4.2 (I will update soon) and the latest 19 version is 19.0.6 (https://nextcloud.com/changelog/#latest19) but https://scan.nextcloud.com shows “Latest patch level” as okay. I pressed “trigger re-scan” to. Could that be a bug with https://scan.nextcloud.com?
