Thank you for connecting with the Community, @Nacho978.

I'll walk you through how to refresh data in the QuickBooks Mobile app.

When you refresh your data, QuickBooks Online App will update it with the most recent data that is currently available. Please also ensure we have a stable internet connection while doing the process.

Here's how to refresh data:

For Android:

1. Go to Menu ☰, and tap More Options ⋮.
2. Tap Settings, then Refresh Data.
3. Tap YES to confirm.

iOS

1. Go to Menu ☰ and tap Help & Feedback.
2. Tap Refresh Data.
3. Note: A message appears if there's a problem getting your latest QuickBooks Online data; refresh it now. It may take a few minutes.
4. Tap Refresh to confirm.

If the issue persists, I recommend uninstalling and reinstalling the mobile app. It allows you to start over with the app.

Please follow the steps below to proceed:

1. Tap and hold the app on your phone.
2. Drag the app to the Uninstall section.
3. Select Yes to confirm.

Once done, visit these links to reinstall the QBO mobile app:

• Android app via Google Play.
• iPhone, iPad, and Apple Watch apps are via the iTunes App Store.
• Get the download link through SMS.

In addition, QuickBooks allows us to create reports to get a complete picture of your company's performance by running profit and loss. Learn how to run them from this articles:
