In this app, I have a logout button that's signed out the user if logged in with email & password or with a google account, the problem happens after signing out and re-launch the app again in the SplashActivity, I do check for the currentUser if is null it should go to the login page, else it should go to the home page, but It seems the app remember the current user even it's logged out before, I tried this solution but it doesn't work
