Google has placed a notice at the top of the Google Search Console removal tool that says, "Cache updates are no longer available." It added that you "can still request snippet updates."
Here is a screenshot, please notice the line at the top with the i symbol:
I will speculate that this brings Google one step closer to fully dropping the cache tool in Google Search. As a reminder, Google removed the cache link in Google Search. But as of right now, you can still manually access the cache option by going directly to it. So for example: [https://www.google.com/search?q=cache:seroundtable.com]
Google did say it plans to drop the cache tool completely at some point...
