Session devs, on their blog, claim the App has no trackers and the only way this could happen is if user allows Google analytics in phone settings (which I guess applies for all apps). How do you explain Firebase appearing in Malcore analysis? Is this accurate? What about Session App downloaded from Fdroid ? Which App version did you test and where was the APK downloaded from?
