CSS not being loaded on first pageview

Hello, many of my pages, mostly review pages (like the example) and also the admin panel, when I try to load the page, it doesn’t load all the CSS on first view. I can only see the page properly after a refresh.

For example, this page: https://www.bestroboadvisors.org/reviews/vanguard/

On first load: https://gyazo.com/cb826e9cb3ae1595baa4a57f7a84c139 – all broken.
Refreshed: https://gyazo.com/0b6af62743b4393c4644c05d104ce0e6 – how it should look.

It’s not affecting all CSS, only some. And it’s happening on my admin panel as well: https://gyazo.com/cb8878e9ee01169185087d824c969b9b

My report number is SNPTNIKL.

Thank you for your help,
Chris
