You'll want to ensure you've installed the correct application on your mobile phone, @diana84. I'll provide more details on this below.
The error message you've encountered results from using a different QuickBooks product to log in to QuickBooks Online (QBO). With this, you can install the QBSE app to access your account.
While the QBSE mobile app has already been discontinued in the Google Play Store, you still have the option to re-download the previously purchased app on your device. For more information, you can refer to this article: QuickBooks Self-Employed mobile app availability update.
Moreover, you might want to check out our latest QuickBooks Solopreneur product, designed for the one-person business. It helps you organize business and personal transactions, track mileage, and measure your business performance.
I'll be around if you need further assistance with managing your QuickBooks account and logins. I'm eager to help. Take care!
