Let me direct you to the right support so they can help you with your invoices to show up, Sggrooming.

In many cases, refreshing the data as my colleague @FateCandylaneT suggested, resolves issues with the mobile application. If it is still now working, I've outlined some additional steps below to help you resolve the problem. I've added these just for you:

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 QuickBooks app from the list, then select Storage.
   4. Select clear data.
4. Power down and restart your device.
5. Uninstall and reinstall the app.

However, if your invoices are still not displaying, I recommend reaching out to our support team via a web browser. This will allow them to double-check the issue and verify your account securely. Here's how you can do it:

1. Sign in to your QBO company.
2. Go to the Help (?) menu.
3. Select the Search tab.
4. Click the Contact Us button.
5. Select the Ask about something else topic in the What can we help you with? page.
6. Provide keywords that describe to your concern. Click Continue.
7. Choose a way to connect (Have us call you or Chat with us).
