Why is BBC Weather not loading in Safari on iPhone running iOS 18.3.1?

Safari loads all 'sub' pages on BBC website (BBC.co.uk) except the Weather sub-page.

Have cleared the 'Cache' twice; Hove restarted the iPhone. I gather it is not possible to reload Safari.

Is there a blocking feature which has been turned on inadvertently?
