Quickbooks app is not opening

I appreciate you doing some troubleshooting steps there, Brandy. Since you're still unable to open your app, we can try logging in to your account through your phone's browser. Let me walk you through the process.
 

You can log in to QuickBooks through your phone's browser, which has the same features as the mobile app. You can browse QuickBooks Online in any browser you prefer. Then, enter your login credentials to navigate through the product.

If unable to log in through the browser, try logging in to a private window.

Here's how:

1. On the top corner of your browser, click the three dots.
2. Select New Incognito Window.
3. Log in to QuickBooks using incognito.

If you can log in using incognito mode, please proceed by clearing your cache to resolve the issue.

If the issue persists, you may contact our QuickBooks Online support team. They can check whether there are issues with your app.

Furthermore, if you're having trouble logging in or can't sign in to your account, refer to this article on how to recover your account.

For future reference, refer to this article if your system is not working or is running slowly: System requirements for QBO products.

I'm committed to providing you with support and ensuring you navigate your QuickBooks smoothly. Feel free to reach out anytime. I'm always here to help and guide you through any challenges you might encounter.
