Google Analytics for Mobile Apps is shutting down.
If you use the free version of Google Analytics, and if you have a free Google Analytics property collecting data exclusively from the Google Analytics Services SDK (Android or iOS), you should already have been notified.
So, if you are one of the many that are using GA for mobile analytics, now would be a good time to step back and think about which app analytics service is the best fit for your mobile app development business.
What alternatives are you reviewing? Do you feel that you should just move to Firebase?
