I can help you with resolving the issue you're having with the mobile app, Stephen.
The issue you're having when trying to access or create an invoice can be caused by your app's cache. In the meantime, I suggest clearing your app's cache to free up space and improve performance.
Here's how to clear the app's cache on your iPhone:
- Tap on the Settings icon and then choose General.
- Click on iPhone Storage and choose the QBO app.
- Tap on Offload App to remove the app and its data temporarily, or tap on Delete App to remove the app and all its data permanently.
For Android:
- Go to the Settings app on your device.
- Scroll down and select App or Applications.
- Find the QuickBooks app and tap on it.
- Select Storage and then tap on Clear Cache.
If the issue persists, you can fix it by uninstalling and then reinstalling the app. Alternatively, you can create or access an invoice through a supported web browser while logged into your QuickBooks Online (QBO) account.
Once resolved, you can check the following article on how to update the invoice template using the mobile app: Customize invoices on the QuickBooks Online mobile app.
