As you know, it can take weeks from the time Google crawls some pages to fully render them. Google's John Mueller said on Twitter Google is working on ways to "getting crawling & rendering closer together." He added that this is still a "looong way off" from happening but Google is working on it.
John said "We're working towards getting crawling & rendering closer together, but that's still a looong way off. Rendering at scale is really hard & expensive (for those rendering & those being rendered)."
Here is the tweet:
