It’s probably a device resolution/display zoom setting that causes you to see ‘Close account’ and not both ‘Close account’ and ‘Log out’ together. Here’s a screenshot from my device which shows both;
But I agree - ‘Log out’ should come before ‘Close account’ for this very reason. Too easy when eye-scrolling from top-to-bottom to tap on the one option you don’t want to do.
Probably a design choice by Monzo to encourage you to stay logged in.
This enables the instant notifications and a lot of the features of Monzo, and you can enable security to protect your app if worried.
Unlike banking apps you may be used to, the Monzo app isn’t intended to be logged out of.
I’ve been with Monzo for several years now, and I think I’ve only ever intentionally logged out once.
When you’ve finished a ‘session’ on the app, simply go back to the homescreen (or switch apps). Next time you need to use the Monzo app, simply open it again.
If you’re concerned about privacy, there’s a setting where you can turn on a lock screen.
