Cannot call useEmulator() after instance has already been initialized

[ithustle]

After a first start my app this warning doesn't show up. But if I refresh the app, it appears:

Error: [firestore/unknown] Cannot call useEmulator() after instance has already been initialized.
NativeFirebaseError: [firestore/unknown] Cannot call useEmulator() after instance has already been initialized.

I don't know why. I've initiated emulator on index.js but before this, I've initiated on App.tsx.

const HeadlessCheck = ({ isHeadless }) => {

    if (__DEV__) {
        functions().useFunctionsEmulator('http://192.168.2.129:5001');
        firestore().useEmulator('192.168.2.129', 8080);
        auth().useEmulator('http://192.168.2.129:9099');
        storage().useEmulator('192.168.2.129', 9199);
        //firestore().settings({ cacheSizeBytes: firestore.CACHE_SIZE_UNLIMITED });
    } else {
        firestore().settings({ cacheSizeBytes: firestore.CACHE_SIZE_UNLIMITED });
    }

    if (isHeadless) {
        // App has been launched in the background by iOS, ignore
        return null;
    }

    return <App />;
}

AppRegistry.registerComponent("ToquePlay", () => HeadlessCheck);

A help, please? It only happens on Android (physical device). Maybe on simulator too, I don't know because I don't use it

This may be the same case as #5650 / #5723 - we're not handling refresh well at all at the moment
