title: Migrate to the Play Install Referrer API Unity3d
body: <p>I received message today from google play</p>
  <blockquote>
  <p>Hello Google Play Developer,</p>
  <p>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.</p>
  <p>Action required</p>
  <p>Migrate to the Play Install Referrer API to track your app installs for the following apps and/or games.</p>
  </blockquote>
