Not really a feature request, but a pretty old bug which makes analyzing user engagement impossible.

When disabling automatic screen tracking via "googleanalyticsautomaticscreenreportingenabled" and doing it manually via SCREENVIEW events, engagement times are logged completely wrong.
Engagement time is wrong by a factor of 10 compared to our ios apps.
