Site fast on desktop, not so much on mobile

Greetings! I’ve been working on a site for a client to improve the site’s speed, and it’s really fast on desktop now, but I’ve been thwarted in my attempts to improve the mobile speed and so I thought I’d post the issue here as you guys are so very helpful. :smiley:

Seems to be the same issue others are have typically had, unused javascript and render blocking resources. I’ve converted the images to WebP and added some code to preload resources which helps a little, and there is code for Segment and LogRocket in the site settings, when I take those out and test it it improves it a little bit but not a huge amount and needs to be there, and the fastest it seems to get with all this on mobile is in the 40s-50s. Any suggestions would be really appreciated!
