Page is reloading even if i used multipage section

Currently, I have two pages, Prod1 and Prod2, each with a sidebar menu, a top menu, and a content section. The top menu and side menu are common, and I’ve used them on both pages using a multipage section with instances. The content changes on both pages, but when I click on the Prod2 tab from Prod1, the entire page reloads. I’m using the WeWeb editor to view the changes. The same happens when I’m on Prod2 and click on Prod1; the entire page reloads. I want to create a single-page app, so how can I achieve that? I want clicking on Prod2 to only reload the content, as the top menu and side menu are multipage sections and should not reload. Only the content and URL parameter should change.

Alternatively, is it because I haven’t published the changes yet? I haven’t published and am checking only in preview mode.

Yes, preview mode will always reload the page, the SPA navigation behavior will be noticeable on the published app only.
