I am wondering if there is a way to obtain from Firebase Analytics statistics the average time spent from users between the two events of "first-open" (that could be interpreted as installation) and the relative potential "app-remove" (uninstallation).
Considering it's an average calculated on "deviceID" or on "InstallationID" basees, i think there should be a calculated metric but i'm not finding it anywhere.
Thank you for your help.
