Black screen signing in

There's a great possibility that this could be a browser-related issue, @whmqb.

Every now and then, the browser becomes overwhelmed with older data that cause viewing and performance issues. Thus, preventing you in signing in to your QuickBooks Online (QBO) account.

Rest assured, I'll share with you the steps to resolve this. Let's start by opening your account on an incognito or private window. You can use either of these keyboard shortcuts:

1. Chrome: Ctrl+Shift+N
2. Firefox: Ctrl+Shift+P
3. Safari: Command+Shift+N

If you're able to log in to your QBO account via a private window, then, you'll need to clear your regular browser's cache. Clearing it will refresh the system.

However, if the issue persists, try using other supported browsers to check if this a browser integrated issue.

Let me know if you have other concerns or questions with your QBO account. I'm just a few clicks away.
