 - Some of the modules that are both in the web SDK and native SDK have a great deal more functionality when they can harness native APIs, like messaging (with background delivery that can start your app if not running), like App Check where you can tie the attestation to device-level providers, Storage where you can do background downloads, Performance where you can start measurements from boot, etc.
 
+### Does it work with New Architecture / Fabric / TurboModules ?
+
+Mostly yes. We have been testing with react-native 0.76 in bridgeless mode for
+a while, and people have been running react-native-firebase with new architecture enabled for a while, and the module works.

+We are not aware of any problems with the react-native-firebase modules themselves. Please let us know if you see anything.
+
+However, there have been ongoing issues upstream in react-native itself with headlessJS on Android. What does that mean for you?

 This may be fixed by creating a `firebase.json` file at the root of your project if it's not there already. If you don't want to change any of the default React Native Firebase configurations, you can leave it empty in the following way:
