CDN only working on my homepage

[woundkrememy]

Hi, I have set up CDN for my site and I can see a tremendous improvement in loading speed.
However, it’s only working on my main homepage. Any other page still load very slowly. I’ve check again using Gtmetrix on these subdomain e.g

myweb.com/about
myweb.com/job

GT Metrix shows that there’s no CDN for those subdomains.
Am I missing something?

Your site doesn’t use the ‘www’ prefix, so that can be ignored.
‘about’ redirects to about-us.
‘job’ redirects 'jobs.
