I'm trying to add Performance Monitoring into my project. My project has been developed in React Native with Android Studio to run my application in a device, and when I try to add "const perf = getPerformance(app)" in my file configuration about firebase, I get this error:

Performance: Firebase Performance cannot start if the browser does not support "Fetch" and "Promise", or cookies are disabled.

I've been looking for this error, but I can't find a solution to solve it.

Thanks.

I'm not sure exactly what you've done or how to reproduce this (https://stackoverflow.com/help/how-to-ask) so I can't say exactly.

I can say that this scripted demonstrator will go from npx react-native init ... of a fresh app to a running integration of all react-native-firebase modules including perf, you can see it in action:
