Expo: A networking error occurred during POST request

[spsaucier]

When I try to initialize Statsig using the Expo client, I'm getting the error specified here: https://github.com/statsig-io/js-client-monorepo/blob/main/packages/client-core/src/NetworkCore.ts#L270

The Expo docs mention that some users experienced a networking error before SDK version 3.1.0, but I am experiencing it on 3.11.0 as well: https://docs.statsig.com/client/javascript-sdk/expo#network-issues
"@statsig/expo-bindings": "^3.11.0",

My provider:

export const StatsigProvider = ({ children }: PropsWithChildren<any>) => {
  const { user } = useAuth();
  const { facility } = useFacilityProvider();
  const [storageProvider] = useState(() => {
    const mmkv = new MMKV();
    return {
      isReady: () => true,
      isReadyResolver: () => null,
      getProviderName: () => 'MMKV',
      getAllKeys: () => mmkv.getAllKeys(),
      getItem: (key: string) => mmkv.getString(key) ?? null,
      setItem: (key: string, value: string) => mmkv.set(key, value),
      removeItem: (key: string) => mmkv.delete(key),
    };
  });

  // Log errors if user or facility data is missing
  useEffect(() => {
    if (!user) {
      logError('Statsig error: No user data available', {
        source: 'StatsigProvider',

        ...user,
      });
    }
  }, [user, facility]);

  useEffect(() => {
    if (user) {
      logBreadcrumb('Statsig: User updated', BREADCRUMB_TYPES.log, {
