Does anyone know how to log off the mobile QB app? The option appears to have disappeared from my screen, leaving me permanently signed in.

Welcome to QuickBooks Community, @mb-mbarry-org-uk!

Let me help you log off your QuickBooks mobile app. Here's how:

1. Go to the Hamburger icon (three horizontal line).
2. Select All.
3. Scroll down and click Settings.
4. Still, scroll down to see the sign out option.

However, if you don't see the Sign out option, it's possible the app needs an update to keep up with your device compatibility. Also, the app stores cache files that can sometimes cause an unusual response to the system. You can clear the app's cache first by following these steps:

• In the QuickBooks Online app:
  • Android: From More Options ⋮, select Settings, then select Refresh Data. Then, tap Yes.
  • iOS: From the Menu ☰, select Help & Feedback, select Refresh Data, and then select Refresh.
     
• In your device Settings:
  • Android: From your device's Settings, select Apps (varies by device), choose QuickBooks app from the list, and then select Storage. Finally, select clear data.
  • iOS: From your device's Settings, select Setting General iPhone Storage and choose an app that's taking up a lot of space. To free up the storage without deleting the documents and data for the app, select Offload App.

If the same thing happens, you'll want to uninstall and update your device first if needed and then reinstall the app to refresh the system.
