Pagespeed Insights returning different page render to actual website

[The Falls Mountain Retreat Blue Mountains]

Trying to optimize wordpress site, had no luck with pagespeed insight plugin despite setting up API etc so fell back to manual checking via https://developers.google.com/speed/pagespeed/insights/
When I run the test on the site the site render returned is a completely different site to the actual website I'm trying to test. I've checked with the hosting company and they say everything ok on their end and when I check the website across multiple devices it is showing up fine. Trying to work out what might be causing this. I have seen a similar post on here about this but no further follow up - hoping someone might be able to point me in the right direction.

I think, that is because page is mainly rendered&styled by scripts applied after page is loaded.

From your html source, I do not see how you did have removed "render blocking" issue?

Are you serving different html page to PageSpeed Insights client?

There is no image or text on your site that is like image or text on PageSpeed Insights screen preview.
