Mobile app properties no longer supported in Search Console
Dear 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 (my app id)
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 APIor the Download button in Search Analytics before the end of March.
