I accidentally logged out of my account. How do you log back into your main account? I don't see any options to do so.

Hi!

When you logged out this menu should have appear:

If it for some reasons didn't start a new account and after you're done with tutorial, click on your profile picture in the upper left corner and there is option to "log in" click there, fill your email and password of your account and you should be back.

You'll see "Log in" instead of "Log out"
