I just integrated firebase to my android and ios app.
The dashboard has an engagement card where i can see the top 3 activities or viewcontrollers that the users engage in. The percentage only add up to 74%, and total engagement time is ~ 2 minutes while the average engagement time is 5 minutes.
As you can see from this image here
But how do I see the rest of screen classes? I am pretty sure my app contains more than 3 classes, and I am quite sure my QA people go through other parts of the application.
