Why on the Dashboard of the mobile app are the expense in the Expense section different than the Expenses in the Profit and Loss Section? Only for the mobile app.

It's possible that the app is not properly synced with the web version, bac4.

Let me share a couple of steps that can resolve common issue when working in the mobile app. 

First, let's clear the app's data. There are two places to clear app data and remove cached data:

• In the QuickBooks Online app:
  • • Android: From More Options ⋮, select Settings, then select Refresh Data, and then choose 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 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.

Once done, open the app once again and check the expense amount is already correct in the Dashboard.

Second option is to uninstall and reinstall the app just in case the amount is still incorrect. Just follow the usual steps of removing an app from your mobile device. Then, you can go to this link to quickly reinstall the application: How to download the QuickBooks Online mobile app.
