Hello,
Be aware that implementing a site-wide change, such as activating the ‘Discourage search engines from indexing this site option, can require a certain period before all your pages are de-indexed.
This process requires Google to recrawl your site and register the changes, which may take a few days, weeks, or even longer, depending on the size of your site.
It’s crucial to provide Google with ample time to acknowledge these changes.
Search engines are not instant in recognizing modifications made to a website. Exercise patience, wait for some time, and then verify again.
If there’s a need to remove a particular page promptly, Google Search Console offers a URL Removal Tool ( https://support.google.com/webmasters/answer/9689846 ) .
This allows you to conceal a URL for approximately six months temporarily.

Requests submitted via the Removals tool typically last for about six months. If you wish to permanently obstruct a page from appearing in Google Search results, you could:
Remove or update the content on your page.
This approach is the most reliable way to ensure that your information won’t be visible in other search engines that may not respect the no-index tag and also safeguard your page from being accessed by others.
Protect your page with a password.
This restricts access to your page, enabling only authorized users to view your content while blocking Googlebot and other web crawlers.
