Currently, Android and iOS have a slight difference in how they utilize the Segment and Firebase configurations and enable/disable features based on it.
Android checks if Segment is enabled and Firebase Analytics is also enabled then Segment's integration for Firebase is used
Whereas iOS checks if Segment is enabled and Firebase is configured properly (i.e. all Firebase keys are present in config) then Segment's integration for Firebase is used
We can achieve parity on both OS by changing the Firebase config as follows:
Both mobile platform teams should have consensus on this updated workflow
Feature flag wiki should be updated
Application codes will need to update as well
