.. Firebase () ITC/App Annie... , , , , ..
EDIT: I think Firebase may be tracking the button trigger, i.e. when updated transactions are updated, and not when the purchase is truly confirmed. For example, the user clicks the IAP button in the application, and then cancels the operation. Perhaps this activity is monitored by Firebase, even if the purchase does not occur.
Just my 2 cents. I will do some tests and I will report here.
