Hey, thanks for the reply. I found something in the network tab, that looks wrong - however I really have no idea.
The first document that loads shows the site without much of the CSS implemented, it seems. The next documents loads images, css, javascript and so on.
However, the same site hosted at Heroku shows something else. There, the first document that is loaded says “You need to enable JavaScript to run this app.”. The Heroku version is not built in Gatsby though, but the site renders perfectly when i build locally and test in with “npm serve”, so it seems unlikely Gatsb is the problem.
Does this give away any clues to anyone?
Edit:
I removed all the @fortawesome/react-fontawesome icons and deployed to Netlify again. The “blowing up” of the icons disappeared, naturally, but still there is a little “twitch” on the h1 especially. When i look at the network tab and refresh, i can see that the “twitch” occurs when the css-files are loaded, which of some reason happens *after * the first document (the page itself) loads. This seems very odd, because the first ducument has colors and everything (as seen in the image), so I would really appreciate if someone had any tips for me as to what could be the problem here.
