LaunchDarklyClientError: Unknown feature flag on Android

[nadSTC]

Describe the bug Getting a 'not found' error when trying to retrieve feature flags on android specifically. My project is in react native using expo. I can confirm that the exact same code works for iOS in both device and simulator. Here is how i set up my launch darkly client

I can confirm that all my flags have the SDKs using Mobile key checked as well.

import { ReactNode, useEffect } from "react";
import {
  LDProvider,
  LDContext,
  ReactNativeLDClient,
  AutoEnvAttributes,
} from "@launchdarkly/react-native-client-sdk";
import envConfig from "../util/env.config";
import { useAuth } from "./AuthContext";

const client = new ReactNativeLDClient(
  envConfig.launchDarkly.mobileKey,
  AutoEnvAttributes.Enabled
);

export const LaunchDarklyProvider = ({ children }: { children: ReactNode }) => {
  const { user } = useAuth();

  async function identify() {
    const context: LDContext = {
      kind: "user",
      key: user?.email || "anonymous",
    };
    await client.identify(context);
  }

  useEffect(() => {
    (async () => {
      await identify();
    })();
  }, [user?.email]);

  return <LDProvider client={client}>{children}</LDProvider>;
};

I'm retrieving my flag values using useBoolVariation, useStringVariation etc.

Expected behavior Feature flag values should propogate

Logs same error for all my flags in android

 LOG  error: [LaunchDarkly] error: LaunchDarklyClientError: Unknown feature flag "<featureFlagName>"; returning default value false., context: {"kind":"multi","user":{"k
ey":"anonymous"},"ld_device":{"envAttributesVersion":"1.0","manufacturer":"Google","m

If you are running Android in debug in the simulator, there is a known issue with Flipper blocking streaming network connections in debug mode. Please see this pinned issue and see if this resolves it.

Newer RN and Expo should not encounter this issue. I've updated some readme and example information with notes about what versions function correctly in development builds.
