We have a ReactJs application served from S3 with dynamic content on https://teletext.io https://teletext.io. All content (eg texts) is loaded asynchronously from a CloudFront distribution and I can confirm this is indexed properly by Google (see https://www.google.com/search?q=site%3Ateletext.io https://www.google.com/search?q=site%3Ateletext.io). The only thing we cannot seem to get right are the meta title and meta description. If you set that asynchronously based on the React page you are rendering, Google only seems to pick it up in about 10% of the pages. So the SERPS doesn't look as pretty as you would like. I didn't found a solution for that yet. :-(
