Missing ~10% data for both tracker installs and revenue reports

[NudeNULL]

Using the latest AppMetrica SDK version, 5.2.0, linking the Facebook tracker and sending all revenue events as soon as they are received from the monetization sdk.

But constantly getting lower revenue than the one showed in the monetization dashboard, same for user acquisition, even if the Referrer Decryption Key is used, for every country there are missing installs, and its the same % everywhere, 10%-15%...

Is actually AppMetrica losing some data on its way to the server or the SDK is not always initializing on some devices or for some specific users?
