Why has my old account and contacts disappeared?

Hi there, dj.

Before we begin, I want to make sure I provided the right information to address your concerns. 

Are we referring to your account in the chart of accounts and contacts such as customer contacts, vendor contacts, or your QuickBooks Online account and contact details? I'd also appreciate it if you can send me a screenshot of the page where you're trying to navigate.

Feel free to tag my name and add a few details to this Community thread. I'll get back to you as soon as I can. Keep safe!
