That is what I noticed for mobile analytics (firebase analytics) as well. It's nice looking at the daily active users and such, but you don't really get any actionable data from it.

For me, a much better approach would be my own analytics, tailored to my product using simple sql statements.

For example how many of my users are tracking mainly dividends vs tracking their portfolio? To get such data I would have to invest more time into setting the right firebase analytics flags than just creating a BI Dashboard that uses one sql query under the hood.
