Hi there,
I just enable the APO on this site: https://thebinaryoptionsblog.com/
However, when I tested here: Free Website Monitoring Tools | Uptrends, I am not getting this:
> cf-edge-cache | cache, platform=wordpress
> The cf-edge-cache headers confirms the WordPress plugin is installed and enabled.
And when I tested with GT Metrix and Lighthouse, the results are much worse than before.
I am on kinsta, using their CDN and also Perfmatters plugin.
Another strange thing is that my main version is without www and in the image below, shows that the APO is installed on www version.
