Is Prerender.io/React going to negatively impact our SEO efforts?

[Wagada]

On any page on the site (https://theadventurepeople.com/), the same short code appears.

Having investigated Google index pages, Google's cache and Fetch & Render, it does look like Google can view the content and index it, but we're not 100% convinced.

Background technical information from the web developer:

• The website is a single page application built using React.
• The site is setup with Prerender: https://prerender.io/  (which renders the javascript in a browser, saves the static HTML, and returns that to crawlers).
