I'm building an Angular app that supports English and Japanese.
domain.com, is displaying in Japanese.
domain.com/en, is displaying in English.

domain.com and redirect the user to the right page based on user browser language.

But for some reason, when I search using Google in Japanese, the first result is
domain.com (which is correct). But the title and description are in English. The interesting part is when I check the cache version of the site (there's a little triangle icon next to the domain, clicking it will be able to see the cache version of the site), it's in the correct language.
I have no idea why it behaves like that.
