  No

• Can you give us steps to reproduce with a minimal, complete, and verifiable example? Please include any specific network conditions that might be required to reproduce the problem.

1. Create Auth object by:

Auth.Builder builder = new Auth.Builder().setAppClientId(COGNITO_CLIENT_ID)
        .setAppClientSecret(COGNITO_CLIENT_SECRET)
        .setAppCognitoWebDomain(COGNITO_WEB_DOMAIN)
        .setApplicationContext(applicationContext)
        .setAuthHandler(new CognitoAuthenticationCallback())
        .setUserPoolId(COGNITO_USER_POOL_ID)
        .setSignInRedirect(COGNITO_APP_REDIRECT)
        .setSignOutRedirect(COGNITO_APP_REDIRECT);
this.auth = builder.build();

2. Successfully Login User.
3. Request this.auth.isAuthenticated();

Expected result: isAuthenticated() return true;
Actual result: isAuthenticated() is always false, even after successfully login.

In SDK source code in the class AuthClient I’ve found that for caching session for key clientId
is using pool.getAppId(). In the getSession() method in same class is also used pool.getAppId() for get cached session. But in isAuthenticated() method in same class value of pool.getAppWebDomain() is using as a clientId:

public class AuthClient {
...
    public boolean isAuthenticated() {
        AuthUserSession session =
                LocalDataManager.getCachedSession(context, pool.getAppWebDomain(), userId, pool.getScopes());
        return session.isValidForThreshold();
    }

...
protected void getSession() {
    ...
        // Look for cached tokens
        AuthUserSession session =
                LocalDataManager.getCachedSession(context, pool.getAppId(), userId, pool.getScopes());
...
    }
...
private void refreshSession(final AuthUserSession session,
                                final String redirectUri,
                                final Set<String> tokenScopes,
                                final AuthHandler callback) {
        new Thread(new Runnable() {
           ...
                    // Cache session
                    LocalDataManager.cacheSession(context, pool.getAppId(), username, refreshedSession, pool.getScopes());

        ...
    }

Because session parameters were cached by one key and requesting them by another isAuthenticated always return false. Is this a bug?
Thanks!
