Unable to change Twitter image via Social Tab

Hi – this topic may be in a different thread. I have searched for it but can’t find.

I added a Twitter image on a page via the Yoast SEO > Social tab
This displayed correctly in Twitter when sharing a link.

I then decided I preferred a different image so changed it.
The new image wouldn’t display. It still showed the first image.

I have tried several attempts to remove completely, add other images etc but it still displays the very first image I tried when sharing a link to that page on Twitter.

In the page source window the meta name twitter:image is pointing to an image that isn’t being displayed. No matter what I do I cannot get this to change.

Is there any way of ‘scraping’ the Twitter cache like you can in Facebook debugger or some other way of resolving this?

Thanks
