My purchase receipts aren't uploaded after emailing them or taking a snap on the app,

Thank you for connecting with the Community, @info11.

I understand you need to upload receipts to your account. 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 latest data and display recently uploaded receipts. Please also ensure that we have a good internet connection while performing the method.

Here's how to refresh data:

For Andriod:

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, I am adding a link that you can use for future reference to know the different features available on your device and how to manage your receipts :

I'll be waiting for your response if you have more queries. I'm determined to assist you in reaching your goals. Have a wonderful day!
