Unable to move CSS resources to the footer and load only critical CSS


I am trying to optimize my site for a 100% page load score. The main issue is that I am unable to defer the CSS resources to the footer even after setting up the advanced configurations correctly.

I entered the ‘critical css’ in the ‘above the fold’ section and moved all the other CSS to the footer. But due to some reason, the deferring is not happening. Can you please login and check this issue? I have enabled support access for https://fresco.wpmudev.host.

Can you also please check if I have entered the above the fold CSS correctly?
