I'm sorry to hear that you're having trouble using the app after the recent changes, JamieBetts.
Before we proceed, could you clarify what specifically changed in the invoicing process or layout that is causing confusion? Alternatively, is there a particular function that isn’t working as expected? Any additional details would be greatly appreciated.
In the meantime, if you're using QuickBooks on an Android or iOS device, you can easily access the Invoices section by tapping the Menu button.
Also, you can log in to your QBO account in any supported mobile web browser and perform the task that you need to finish in QuickBooks.
Once you've successfully created an invoice, feel free to reference this link that provides guidance on managing invoices in the QBO mobile app: Manage invoices and payments with the QuickBooks mobile app.
If you have any further questions, please don’t hesitate to reply below. We're here to assist you.
