The HUB is showing NO updates, but as I have accessed admin wp-admin/update-core.php now I see the updates in the HUB as well. There were WP Core update, Theme update and 2 plugin updates. But if there is updates available and I have not checked the Updates page in admin yet then in the HUB. Does it wait for the next sync period? Does the Automate also work like this as it is linked to the HUB (which updates 2 times per day), if so that is a potentially serious security risk!
