백 서버 터미널 오류

        const token = await EncryptedStorage.getItem('refreshToken');
        if (!token) {
          SplashScreen.hide(); // here
          return;
        }
        ...
      } finally {
        SplashScreen.hide();  // here
      }
    };
    getTokenAndRefresh();
  }, [dispatch]);

강의 따라서 SplashScreen.hide() 잘 해주었는데,

이 상태에서 멈추고 갑자기 back 서버 터미널이 무한 로딩되는데... back 서버를 껐다가 다시 켰는데 로그인이 되어있으면 안되는데 되어있는 상황입니다

잘 되다가 갑자기 이러니 당황스럽네요...ㅎㅎ

메트로 서버에서는 이렇게 나오네요

 LOG  Running "FoodDeliveryApp" with {"rootTag":11}
 LOG  !isLoggedIn true
 LOG  check location granted

백 서버를 껐다가 켠건데 왜 로그인이 되어있는 상태로 나올까요?
