Hi NiaKova,
Do you mean you are pressing back on the browser? This will take you back to the bases if this is what you were in last. If you are navigating articles you can use the navigation buttons at the top of the article to go back and to go back to the home page of your current base.
You should see a house for home, a green arrow to go back, and a yellow circle to see all the articles you have visited from previous decisions to help show you how you got to the current article.
