Has the layout changed on the app? Why has my invoice template changed?things are missing from the invoice I previously customised.

When you mention 'on the app', are you referring to the QuickBooks Mobile app or the QuickBooks Online desktop app? Providing more details will help us offer you a more accurate solution, @hello212.

In the meantime, please log into your QuickBooks account using a web browser to check if there have been any changes to the layout of your customised invoice. If there are any changes, review the Audit log to identify the last action taken with your invoices.

If you don't see any changes to your invoice when using a web browser, perform these troubleshooting steps for the QuickBooks Mobile app:

For iOS,

1. Go to Settings, then tap General.
2. Tap iPhone Storage, then tap the QuickBooks Online app.
3. Tap Offload App.

For Android,

1. Go to Menu ☰, then tap More Options ⋮.
2. Tap Settings, then Refresh Data.
3. Tap YES to confirm.

When you're using the QuickBooks Online desktop app, refer to the Troubleshooting tips section in this article: Download and use the QuickBooks Online desktop app.
