Scroll down and tap Log Out.
Close Safari and launch the Mevo app.
Once you are connected, tap the red button, followed by the Facebook Live logo.

You will be brought to your Safari and will be able to login to another Facebook account.
Alternatively, you can clear your Safari browser's history and website data in the iOS device settings. This will also log you out of your Facebook account.
