I've just tried it, I seem to have trouble loading the page from mobile (Firefox on Android), I get a popup saying:
"Request failed: error loading dynamically imported module: https://mix-n-match.toolforge.org/vue-components/site_stats.js"

@picolaton
I have found out in the meantime that the problem was with my Adblocker. Have you tried without one?
