Google has issued thousands of AMP issue detected notice through its Google Search Console.
If you do not know about AMP, AMP is a Google project that is working to make sure web pages load really fast. We have recommended using AMP to improve pagespeed on WordPress websites. The AMP Project is an open-source initiative by Google to make the web better for all.
However, everyone who got the new notification at Search Console had the subject “New AMP issue detected for site,” with a detailed explanation about the issue. The AMP message of the notification reads:

Why Google is Sending AMP Image Issue Notice?
Google has changed the recommended AMP image resolution again. The new AMP image size requires your images to be at least 1200pixel in width. Google first changed the AMP image size recommendations a year ago.
Previously, The Google AMP’s image recommendation asked for the image size to be a minimum of 696px wide. However, as per the new rule, Google wants every featured image to be at least 1200px wide, almost doubling the width from 696px. Google has also modified the total pixels from 300000 pixels to 800000 pixels.
Google is sending new notifications to those who still have not addressed the issue featured image issue. Shortly after the emails reached inboxes of millions of webmasters, we found people talking about it loud and clear on Twitter.

Webmaster Trends Analyst at Google, John Mu stated the reason in his Twitter handle.
That was updated some time last year, the only recent change was that we wanted to make sure sites knew about this and sent notifications via Search Console.
