i experience the same issue into my developer account. The number of (Daily Active Installs - Daily active uninstalls) for a period of time of 30 days is 3 times less than the number of (Active Installs Day 1 - Active Installs Day 30)
The Google play documentation says:
"For data about the current installed population of your app, refer to “active” or “total” metrics rather than trying to sum up daily metrics. The daily metrics are meant to provide immediate feedback about your app’s recent installations. “Total” and “active” metrics will give you the most accurate picture -- they take into account app reinstallation, data that is received after the daily report is generated, devices that are no longer active, and more."
But 3 times difference on numbers is very big and most importantly very confusing
any other experience?
