I'm here to clear things out for you, adam-dot-net.
 

The regular desktop application was discontinued last April 20, 2021. The one you're using is the app exclusive to QuickBooks Online Advanced users. We've launch this to provide more innovative accessibility and streamline workflows.

The program was made more stable for power users who spent several working thanks to its multi-tab and company switching features. If you opt to access your account through the application instead of a web browser, you can remain logged in for up to six months unless you deliberately choose to log out.

In addition, a navigation map view similar to the home page found in QuickBooks Desktop will be available. This speed up and simplify your tasks by offering a flowchart of linked procedures.

To avoid unexpected behaviors, we recommend running the software through a Windows 64-bit computer. If you're having trouble, we have a dedicated support team for QBO Advanced to ensure your enquiries are sought to. Here's how to contact them:

1. Go to the Help icon.
2. Select the Search tab, then click Contact us.
3. Enter a brief description of your issue in box.
4. Hit Continue, then select Call or Chat.
5. Follow the on-screen instructions.

I also encourage posting the bug that you encountered here. This way, the Community Team and other product experts can help you out.
