Page Speed issue on mobile

I am trying to optimize the speed of a website and it’s all good on desktop, but on mobile it’s not great. In the image below you can see what causes most of the slow speed, but i don’t know how to fix it.

Webfont
I have uploaded the fonts i used and changed the settings to ‘swap’ and picked a font. So i don’t know what else to optimize.

CSS
I have the ‘Minify CSS’ setting on, but i still get this from Webflow. What could be the problem here?

You do not have any control over your Site. You can’t inline your css files unless you export and make it manually. This type of pagespeed problems won’t ever be resolved.
