I have the similar issue for my site huglero.
Actually I can’t deny that I could finally have 2x, 3x,faster speeds thanks to litespeed cache after tying and failing all the other ‘best’ caching plugins.
However, while gtmetrics shows 95-97% Google pagespeed has no mercy about this and always keeps showing mobile speed as ~30-32 points while desktop is ~70.

And whatever I tried, I couldn’t achieve to remove this ‘preload key request’ for fontawesome font which delays the page load about 2500ms-3000ms which is a total disaster.
What can I do about that? Please help me.
