I saved it but the live site did not change

Save alone keeps a draft. The public site changes only after the matching publish button.

• A site built in Core Bridge goes public with Go Live on the Core Bridge preview.
• A page built in Page Builder goes public with Publish on that page.
• A blog post goes public with Publish in the post editor. Update is the same button after the post is already published.

Discover pages does not publish anything, and it does not run when you click Go Live.
