How to log out of QB self employed online using iPhone 12?

Hi there, nepsvcpro-neptun. Allow me to assist you in logging out of the QuickBooks Self-Employed mobile app.

You can sign out of your QuickBooks Self-Employed account by tapping the profile icon in the upper-right corner of the app and then select Sign out.

If you're still unable to sign out, you can reset the app's data to refresh it.

Here's how:

1. Click the QuickBooks Self-Employed icon and go to Help & Feedback.
2. Choose Reset App Data. 
3. Select Refresh.

If it still doesn't work, we can uninstall and then reinstall the QuickBooks Self-Employed app to start in a clean slate.

Please let me know how it goes by leaving a comment below. I'm always here to assist. Have a great day!
