Thank you for joining this thread to share your concerns, @LorraineD2023. Let me share some insights about this QuickBooks App.

As shared by my colleague MariaSoledadG above, QuickBooks Online Windows and Mac desktop apps are no longer supported as of April 20, 2021. Thus, it's the reason why you're unable to download it from your google play or app store.

In the meantime, we recommend accessing QBO through your preferred browser by signing in at qbo.intuit.com, or you might consider downloading our QuickBooks Online mobile app. For a detailed step-by-step process, please check out this article: How to download the QuickBooks Online mobile app.

We appreciate your trust in QuickBooks to meet your accounting needs. We value your business and are committed to ensuring your success with our products and services.

I'll be around if you need further assistance with QuickBooks. I'm very eager to help. Take care always.
