Is anyone else having issues with QB Online this morning?

Hi there, @PM Controls.

Let me share some troubleshooting steps to fix the issue so you can successfully open your QuickBooks without issues.
 

Since you can't open any of your accounts in the Chart of Accounts, you can perform the basic browser troubleshooting steps. The issue you encountered may be due to a browser cache-related issue. Your browser saves files to load websites faster on your next visit. But over time, it'll get outdated, which can cause errors and performance issues using the program.

First, you'll want to restart your browser. Then, try creating an invoice to see if you can access your accounts in the Chart of Accounts in an incognito or private browser. You can use these keyboard shortcuts to launch a new private window:
 

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

If it works on the private browser, go back to the regular browser and clear your browser's cache. Otherwise, you can use another supported browser.

Actually, there have been a few other posts about it.  I don't see how it could be a browser issue.  

Definitely sounds like a QB issue.
