Describe the bug

I am using Amplify authentication to signup/login and get an authToken that I use to authenticate with our api. Everything works fine until the access token’s expiration. After that point every time I try to get a new token (using Amplify.Auth.fetchAuthSession()) I only get the same expired token. I am fetching the auth session on app’s start and every time I get a 401 code response from our api, every time the token I receive is the same. The only solution to get a new valid token is to Log out -> Log in -> Amplify.Auth.fetchAuthSession but I don’t think that’s the intended behaviour.

Reproduction steps (if applicable)

1. Login using amplify and get the accessToken
2. Wait for the token to expire
3. Try getting a new accessToken by calling Amplify.Auth.fetchAuthSession()
4. Notice that the token I get is the same token as the initial one which expired.

Code Snippet

override suspend fun getAuthSession(): Outcome<AuthSession> {
        return try {
            val session = Amplify.Auth.fetchAuthSession()
            Log.i("AmplifyQuickstart", "Auth session = $session")
            keyValuePersistentData.setValue(
                TOKEN_KEY,
                (session as AWSCognitoAuthSession).userPoolTokens.value?.accessToken
            )
            Outcome.success(session as AuthSession)
        } catch (e: Exception){
            Outcome.failure(e)
        }

    }
