Nuxt performance on mobile browsers



Hello everybody.

I am currently working on a new website for my company, Intrace.
We have decided to build it with Nuxt to try out something new. The thing is that according to PageSpeed Insight it is performancing like 96% on desktop, but poorly on mobile (4%-ish).

I have no clue why - the page is loading like a charm when I do visit it on my phone (even on hard refresh).

Have any of you experienced this before?

Many regards


What app to check that performance? I am absolutely a beginner here
