Google is developing a new notification system for the Play Store that will inform users when an installed app has been removed, providing tailored messages based on the number of affected apps. Currently, Google Play Protect only alerts users about harmful apps but does not notify them about apps that are voluntarily removed or delisted for policy violations. The new system aims to address this gap by notifying users that apps will no longer receive updates, which is a concern for security and functionality. There is no specific timeline for the release of this feature, and the findings are based on code snippets that may not all make it to the final version.
