Logging out with SpringBoot and Goolge doesn't work

Question

I have an app where I can log in via Google oauth. That works so far. The only problem is that when I click on a button (logout), I'm not logged out of Google, as should be expected. I can then simply launch the app normally, as if I had previously logged in. Only when I explicitly log out under Google does the login work again.

Here's my code:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().antMatchers("/", "/login", "/oauth/**").permitAll().anyRequest().authenticated().and()
            .formLogin().permitAll().loginPage("/login").usernameParameter("email").passwordParameter("pass")
            .defaultSuccessUrl("/list").and().oauth2Login().loginPage("/login").userInfoEndpoint()
            .userService(oauthUserService).and().successHandler(new AuthenticationSuccessHandler() {

                @Override
                public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
                        Authentication authentication) throws IOException, ServletException {
                    System.out.println("AuthenticationSuccessHandler invoked");
                    System.out.println("Authentication name: " + authentication.getName());
                    CustomOAuth2User oauthUser = (CustomOAuth2User) authentication.getPrincipal();

                    userService.processOAuthPostLogin(oauthUser.getEmail());

                    response.sendRedirect("/list");
                }
            })
            // .defaultSuccessUrl("/list")
            .and().logout().logoutSuccessHandler(oidcLogoutSuccessHandler()).invalidateHttpSession(true).clearAuthentication(true).deleteCookies("JSESSIONID").and().oauth2Login();
}


  private OidcClientInitiatedLogoutSuccessHandler oidcLogoutSuccessHandler() { 
        OidcClientInitiatedLogoutSuccessHandler successHandler = new OidcClientInitiatedLogoutSuccessHandler(clientRegistrationRepository);
        successHandler.setPostLogoutRedirectUri(URI.create("http://localhost:8080/login"));
        return successHandler;
    }
