I can't reach settings page or anything similar either.
Whenever the cog is clicked browser goes to "/start" and a page with "Enter your email" is shown.
Clicking Cancel or Continue without filling email takes me to page before.

The quick action bar on the search results page also has a smaller cog icon and other icons on it that will allow you to change several settings without logging in, but you must have javascript enabled to access them.
