Strange statistics in Google Play Developer Console

Question

Today I noticed strange statistics in my Google Play Developer Console in one of my application

It is about Final installs on active devices:

17 July - there was big leap caused by including pre-install. I don't known why, beause I don't think my app is pre-installed by any provider.

18 July - installs on active devices falled to 0

As you can see daily installs are still correct.

Have you got any idea why this is happening?

Answer 1

I've had this exact same problem today. Also, it no longer shows the total number of of installs for apps in the list under "All applications".

I shouldn't worry about it. They've been making changes and must have messed something up.
