I am a developer from Duolingo Beijing Office. Duolingo App is using Zendesk for support pages (https://support.duolingo.com). However the website loads very slow in China, I need to wait 1-2 minute for the page to be rendered.
I checked the Chrome console, and found the page is using jquery-ui files which are hosted on Google, so they cannot be accessed in China:
Could you help fix this issue? I think change the jquery-ui to custom asset urls should fix this problem, and won't take big effort.
