Hi @Loran, thanks for taking the time to post. I am sorry to hear about the trouble with the fonts. Is the user who is trying to view the site actually in china?
Could you help to share a read-only link to the site: Share a read-only link | Webflow University
And also, the published site link ?
If you can help to provide an exact android device model, i.e. Huawei model X etc.
As a note, the Chinese seems to block google scripts including google fonts, so if the user is in China, the font is probably getting blocked.
