Web publishing says published successfully but snapshot shows old version

Hi! I am trying to publish a website after saving a new version.

Under the Build section > Page Selector > Project History - I've hit Save and it has saved a new version.

I've then gone to Settings > Web Publishing > Publish.

I have previously deployed successfully to both a custom domain and a FlutterFlow domain with no issue. It's odd because all the help guides say to follow the above steps, but when I visit my custom domain it's still the old version.

I've hard refreshed the browser as well as restarted the computer to clear out the cache but neither has worked.

Any help would be great!
