Without prerender.io, is google able to render & index geographical dynamic content?

[imjonny123]

One section of our website is built as a single page application and serves dynamic content based on geographical location.

Before I got here, we had used prerender.io so google can see the page, but now that prerender.io is gone, is google able to render & index geographical dynamic content? I'm assuming no. If no is the answer, what are some solutions other than converting everything to html (would be a huge overhaul)?
