Google is sending out notices via Google Search Console with alerts about “mobile-first indexing issues detected”. In those emails, it reveals the issues Google has when it comes to moving a site over to mobile-first indexing. It also states “Google expects to apply mobile-first indexing to all websites in the next six to twelve months.” The email alert will also outline the error(s) which prevent the website from being moved over to mobile-first indexing.
This month, GSC began alerting us to mobile-first indexation issues across our sites. In no uncertain terms: “Google expects to apply mobile-first indexing to all websites in the next six to twelve months.” @rustybrick @jenstar pic.twitter.com/D6nTfClrTw

Why should you care? If Google has trouble accessing your website with the mobile-crawler then it might impact the indexing as well as the ranking of your web page(s) in Google. Clearly Google is trying to be proactive. The company is notifying sites that are not yet moved over to mobile-first indexing; and, providing specific advice on what those sites need to do to become mobile-first indexing ready.
