Does not work in a private window. When you click the tunel bear icon, it takes you to the login page and after logging in, the icon remains grey and you have to repeat the process again and again until you realise it's just not working in private mode.

The login screen has the register button instead of the login button so you would think you could login in a single click but instead it's again one of those stupid UX dark pattern situations that put's you in a register form by default...

Once logged in in a normal window, I notice there are no servers for Russia or Poland... Too bad.
