Cant see invoices in app. tried refreshing a few times

Welcome to the Community space, asset.

I understand the importance of having your invoices in the QuickBooks app. Rest assured, I'm here to help you address this issue and find a solution that works for you.

Typically, you should be able to see your invoices in your QuickBooks app. Since it currently doesn't show on your end, we can take troubleshooting steps to rectify this.

Here's how: 

1. Change the Wifi data connection on your device to 4G (varies by device).
2. Close and restart the app.
3. Clear app data. To do this:
   1. Open your device Settings.
   2. Select Apps (varies by device).
   3. Choose the QuickBooks app from the list, then select Storage.
   4. Choose Clear Data.
4. Power down and restart your device.
5. Uninstall and reinstall the app.

Then, let's ensure that your app is updated. 

In the meantime, you can log in to your QuickBooks Online account using a web browser. From there, you can see your invoices. For more details, please check out this article: View sales transactions in QuickBooks Online.
