Google AMP reports now differentiate between critical and non-critical errors
Google Search Console has upgraded the AMP error report to show which errors are causing your AMP content to not be indexed in Google.
Google has announced they’ve upgraded the AMP reports within the Google Search Console to “clearly differentiate between the critical issues that would prevent your page from being shown in the search results, and the other non-critical issues that would be good to fix.”
So those errors labeled as “critical” would mean Google cannot index that AMP content, and thus it won’t rank in the search results. The non-critical issues are more likely around richer results that do not prevent the content from being indexed but prevent it being enhanced in the search results.
Here are some screen shots showing the new critical notices:
