Hi James thanks for replying, I can take the Coming Soon page down but it would need to be for a specific time window, so if you got back today I could take it off for you to look at.
In terms of the 1.5MB background image, that doesn’t really present a problem here for us because we can see this image (and other content) load in separately after the ginormous ‘wait’. It also hangs in the same way on the WordPress Dashboard (publishing/updating a page etc).
Our work internet isn’t very good so I think the wait time is a bit less from other computers but there’s still a significant ‘wait’ wherever you load it in from.
