Real-Time Training Website Sitemap Re-sync aft Modified

How long should it take for the sitemap to be re-synced after content on a page is modified? I have a sitemap that updates the Last Modified date accurately but the sitemap does not show it has resynced in the knowledge hub. Chat bot still references past data that has been removed from the website.

@Simone Do you have any insight? As far as i can tell on all my chatbots the real-time training feature for website is not resyncing when website gets updated.
