Thanks tony61-

I'd recommend calling in for additional troubleshooting, we are working through accessibility issues with the app, but the above workaround to unblock cookies and clearing the history/cache should allow access via browser. 

Our agents via phone would be better able to identify what might be the issue using screenshare and further probing on the issue. Follow the steps below for a callback if that is preferred:

1. In your QuickBooks Online, click the Help menu in the upper-right corner.
2. Select Contact us and enter the details of your concern.
3. Click Let's talk and choose Chat or Get a callback.
4. Enter the needed information.
