I am setting various remote config values using Firebase for an Android app. The metrics (KPI) I care about most is average engagement time and engagement time per session. How can I view Firebase analytics with a comparison that is based on what Remote Config values where set for a user?
To be clear. I need to know, If I enable feature "A" do users use the app for more or less time.
I have also looked at A/B testing and can find no metric that is based on engagement time.
A backup question. Is app engagement time not important to other developers? If so why? Maybe I should be looking at something else as a proxy?
In addition I have linked Firebase to GA4. A solution involving Google Analytics would work just as well.
