That's not true. Google indeed waits for async content to load for a given amount of time. You can inspect this from the Google webmaster tools.

I did a lot of tests on this and Google just didn't wait, no matter the configuration. I tested using webmaster tools. The App was built using React, and I ended up implementing SSR to fix the problem. There are a lot of posts that hack this embedding JSON directly on the page. I didn't find any post that figured out a way to make this works through async API requests. I would thank you if you point one in that direction. Maybe I'm doing something wrong.

Were you using react-router by any chance?

I've bookmarked this site: "Testing a React-driven website’s SEO using “Fetch as Google" https://medium.freecodecamp.com/using-fetch-as-google-for-se...

That talks about this. Not had a chance to verify this. just a fyi.
