We haven't received any reports regarding Chrome users experiencing issues with QuickBooks Online. We can do browser troubleshooting steps to get rid of any cache-related issues.
Let's try using a private browser since it doesn't store cache files. You can also use other browsers (such as Mozilla Firefox, Internet Explorer, and etc.) because each of them stores different sets of cache files.
The steps above help resolve browser-related issues, Grantsman.
If you've followed the troubleshooting steps given my colleague and got the same result, please give us a call. We can check what's causing the issue and we'll fix it for you. This way, you can access your QBO account again.
