All my data is missing ...invoice...quotes....expenses etc

This is uncommon, kool.

Let me make it up to you by ensuring this gets resolved.

The issue with retrieving your transactions could be browser-related. The outdated stored cache can affect the performance of the program.

Let's access your QuickBooks Online account via a private window. Doing so helps us determine if there's an issue with the browser. Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + N

Once logged in, open your transactions. If it works, clear the browser's cache to ensure the program performs efficiently. Otherwise, you can use other supported browsers. They also provide the best and most secure experience with QuickBooks. 

In case none of this fixes the problem, I'd suggest contacting our QuickBooks Support Team. They're equipped with tools to check the cause. It'll also allow them to submit a ticket to our engineering team to alert them about the issue if necessary.

Furthermore, I've added these resources that'll help you manage your sales and expenses transactions. Browsing these articles ensure your record is accurate:

• Manage Customers and Income
• Manage Suppliers and Expenses
