React Native Firebase version 23.x.x introduces a modular API for Remote Config, shifting from class-based instances to standalone functions. Developers now pass the configuration instance as an argument, mirroring the Firebase Web SDK v9's design. This change centralizes logic and improves code organization for remote configuration management.

The update requires a new implementation pattern, with functions like `fetchAndActivate(instance)` replacing the previous `remoteConfig().fetchAndActivate()` method. A provided service pattern demonstrates how to wrap initialization and value fetching into reusable utilities. This approach helps manage cache intervals and error handling for more robust app configuration.

Adopting this modular structure aligns React Native development with modern Firebase practices, potentially simplifying cross-platform codebases. Developers should initialize the service early in the app lifecycle, using `try/catch` blocks to handle network failures during the first fetch. The change underscores a broader industry move toward tree-shakable, functional APIs in mobile development.
