Google has sent me and others who have verified mobile app profiles in Google Search Console that they are no longer supported. The email says "at the end of March, 2019, Search Console will end support for app properties." This should come as no surprise to readers here, as we reported this is happening last month. But now Google is sending notifications to these Search Console users to download their data before it goes away.
The email reads:
Mobile app properties no longer supported in Search ConsoleDear Search Console user,
You are the owner of one or more mobile app properties in Search Console. At the end of March, 2019, Search Console will end support for app properties.
The following app properties will be removed from your account at the end of March (maximum 8 shown):
android-app://com.seroundtable.app/ This change does not affect your mobile app's appearance in Search results, nor does it affect any website properties that you own, but indexing statistics for your mobile apps will no longer be available in Search Console.
If you would like to retain your current search analytics data from your app properties, you can download it using the Search Console API or the Download button in Search Analytics before the end of March.
Here is a screen shot:
Here are some screen shots of the analytics and crawl status from the Search Engine Roundtable app - you can download it for free on iOS and Google Play:
