How to logout or switch accounts with the Fortnite mobile app?

In this article, you will learn how you can sign out from a Fortnite Mobile account. Once you’ve logged out, you’ll be able to switch accounts and login to another account. These are the steps you need to follow when you’re in the Fortnite mobile app. I made the screenshots with my IPhone iOS, but steps remain the same for Android:
Instructions
1 Tap on the the 3 lines in the upper right corner.
2 Select the square and arrow symbol.
3 Choose Confirm when you see the question: “Are you sure you want to log out of Fortnite?”.
4 You’ll be redirected to the home screen. From here you can hit Tap to start to login with another profile and switch accounts.
