Describe the bug

I used async-storage implementation from here https://docs.amplify.aws/lib/auth/manageusers/q/platform/js/#managing-security-tokens and with async-storage it working on both iOS and Android, but when i changed implementation to MMKV package - https://github.com/ammarahm-ed/react-native-mmkv-storage , authorization only work on iOS, but not on Android. Also i printed key/value inside the getItem method: key: CognitoIdentityServiceProvider.securityKey.+0101014557.deviceKey, value: undefined

Expected behavior

i expect that signin will work correctly as for iOS

Reproduction steps

inside the Amplify config file:

import Amplify, { Auth } from 'aws-amplify';

const config = {
  ...config,
  Auth: {
    storage: AmplifyMmkvStorage,
  },
};
Amplify.configure(config);

and the storage file:

import MMKVStorage from 'react-native-mmkv-storage';
const MMKV = new MMKVStorage.Loader().initialize();

interface MMKVStorage extends Storage {
  multiRemove(keys: Array<string>): any;
  getAllKeys(): any;
  multiGet(keys: Array<string>): any;
}

export const storage: MMKVStorage = {
  setItem: (key: string, value: string) => {
    MMKV.setString(key, value);
    return Promise.resolve(true);
  },
  getItem: key => {
    return Promise.resolve(MMKV.getString(key));
  },
  removeItem: key => {
    MMKV.removeItem(key);
    return Promise.resolve(true);
  },
  multiRemove: (keys: Array<string>): Promise<any> => {
    const promises = keys.map(key => MMKV.removeItem(key));
    return createPromiseAll(promises);
  },
  getAllKeys: async (): Promise<any> => {
    const stringKeys = await MMKV.indexer.strings.getKeys();
    return Promise.resolve(stringKeys);
  },
  multiGet: (keys): Promise<any> => {
    const entities = keys.map(key => [key, MMKV.getString(key)]);
    return Promise.resolve(entities);
  },
};

And after that import it as AsyncStorage inside the MyStorage example
