We recently migrated our web application to a Client-Side Rendered (CSR) React frontend. We submitted a valid XML sitemap in Google Search Console, but pages show as Discovered - currently not indexed.
When we test live URLs in Search Console, the screenshot shows blank content because the API call times out during Googlebot Web Rendering Service (WRS). What is the recommended architectural solution?
This is a classic JavaScript SEO Rendering Timeout issue. Googlebot renders JavaScript asynchronously, but if your API responses take longer than 5 seconds, Googlebot indexes the initial empty HTML shell.
