I'm happy to hear that you're loving the desktop app version of QuickBooks Online, lapoore.

We've discontinued the app due to limited use. You can continue to use our system by logging into your account via a web browser.

I'm adding this link: System requirements for QuickBooks Online, Accountant, Payroll, and QuickBooks Self-Employed. It'll tell you what computer and browser you need for the best QuickBooks experience.

If you need to know more about the discontinuation, here's the link: QuickBooks Online Mac and Windows Desktop App update. 

If you have other concerns, don't hesitate to leave a comment below. I'm always around to help you with any QuickBooks issues you may be having.
