Hi. No client history (invoices) show on my mobile app. Anyone know how to fix this?

Let me help go over your mobile app and have those invoices show up on your client's history, h2owaterbarcw.

When the application is not fully functional, performing the recommended basic troubleshooting steps will resolve the issue. As an initial step, let's clear the application's cache files. Here's how:

For iOS:

1. Go to Settings and click Setting General iPhone Storage.
2. Choose an app that's taking up a lot of space.
3. To free up the storage without deleting the documents and data for the app, hit the Offload App.

Her's how for Android:

1. From your device's Settings, select Apps (varies by device).
2. Choose the QuickBooks app from the list
3. Select Storage.
4. Hit Clear Data.

Once refreshed, restart your mobile phone, logged back in, and check the invoices on your client's history. If you get the same result, uninstall and reinstall the QuickBooks Online mobile app.

To help you utlise your invoice template in the mobile app, check out this article: Customise invoices on the QuickBooks Online mobile app. It provides steps on how you can modify your sales form's delivery method.
