Why DAU and New users in Unity Analytics much less then in Google Analytics?

My game is currently distributed only via GooglePlay. I use the free plan in Unity Analytics.

In the same day in “New Users” metrics I have:

  • Google Play dashboard: 6300 users
  • Google Analytics: 9655 users (some might download the game from other sources)
  • Unity Analytics: 577 users

Why might this happen? Thank you!

You will want to stay with one source of data and look for relative day-to-day differences. The values will never match. Google counts downloads, we count only those users that actually launch the game.
