Does anyone else have this issue? All my contacts, suppliers, payers have all disappeared. Including past invoices.

Thank you for bringing this to our attention, kmarumo.

I want to ensure you have all the data back to your company file in QuickBooks Online (QBO).

Beforehand, I'd like to know what actions you had taken before discovering the aforementioned concerns? Also, you'll want to ensure that you log in to the correct company that contains all the following data you are referring to.

In the meantime, I recommend performing browser troubleshooting steps. In this manner, we can eliminate common errors that may occur in your company file. Also, this helps the browser to start afresh and work seamlessly.

To start, please open your browser's private window. It isolates the cache that commonly causes a browser's unusual behavior.

Here are the keyboard shortcuts to open a private browser:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + P
• Safari: press Command + Shift +N

Once done, proceed to clear the cache in the browser to prevent this from happening again. If you have another supported browser, you can choose that instead.

Please let me know by adding a comment if you have more concerns with QuickBooks-related matters. I'll be around the corner to lend a hand for help. Have a good one!
