Google is now sending out notices to those webmasters who have a noindex directive in their robots.txt file. Google Search Console is sending out notices that they should be removed because it is not something Google will support after September 1, 2019.
The notice reads "Remove "noindex" statements from the robots.txt of http:" It then says "Google has identified that your site's robots.txt file contains the unsupported rule "noindex". This rule was never officially supported by Google and on September 1, 2019 it will stop working. Please see our help center to learn how to block pages from the Google index."
Google announced earlier this month they are doing away with this support.
Here is a screen shot from Ruban KT on Twitter:
Some folks got many notices:
Interesting - Google is taking this really seriously! Remember to remove 'noindex' statements from Robots.txt! - Seen in Search Console just now. #SEO @rustybrick pic.twitter.com/fe7e23avYH

There may have been a delay?
We've found that despite the 'noindex' being removed some weeks ago when this "change" was first announced - some of our websites still received this alert (indicating an alert delay)🤪.
