I got this email from google, any idea, please
Hello Google Play Developer,
We recently announced that we’ll be deprecating the install_referrer intent broadcast mechanism. Because one or more of your apps uses this intent to track referrals, we wanted to ensure you make the switch before March 1, 2020 . After this date, new versions of the Play Store app will no longer broadcast the install_referrer intent after app installs.
Migrate to the Play Install Referrer API to track your app installs for the following apps and/or games.
The Play Install Referrer API offers better performance, uses a secure communication channel between your app and the Play Store, and offers a more robust solution against spoof and attribution fraud.
We know this change may require some additional work on your part and appreciate your understanding.
