I have the most recent version of the plugin 1.8.27.
I have installed the health check and troubleshooting app. I have run a health check with no obvious issues coming to light. Putting the site in troubleshooting mode doesn’t really help as it all looks fine to me while in admin mode, it is only when not logged in that there is an issue.
I have regenerated the Critical CSS and this has not worked.
I will have to play about with disabling various plugins in live mode to see if that works.
