I'm having big problems with current auto-login feature. It is similar problem as stated here, it was marked as status-completed but I'm pretty sure it isn't, because button that has to be there ("Log Out Everywhere") isn't on its place.
Imagine I'm in town library, I login to Stack Overflow and sometimes to Area51, too. When I'm going out I just click "Logout" on both sites and system says that
Clicking Log Out will clear all local credentials in your browser, and log you out on all devices..
That's a lie. When I click "Log Out", it redirects me to the index and I'm logged out successfully, however, when I click login again, unluckily "Welcome Martin, you're being redirected" appears.
