IFrame does not show new page

I have an iframe as part of my web app, it starts from a default URL (wikipedia)
As the user interacts with the app, some actions trigger the iframe to display a different page.
However I am not able to ge tthe iframe to show the contents of a new page
Tried different ways of doing this: setting triggers to control by component, running javascript etc, no change. The top bar shows the new URL in the iframe, but the actual contents stay the same
Do I need to call some other method to get it to display the actual page related to the new URL?

Hey @Slang!

Do you see any errors in your browser console? It's possible you may have to enable one of the iframe permissions:

Other sites have their own restrictions that prevent them from being embedded (see, for instance, these docs about the x-frame-options header).
