I'm here to help fix the login issue, president-christ.
Usually, this happens when too much cache in your browser can lead to unusual behaviors in QuickBooks. Let's try login into your account using a private browser. This mode will not save any history, making it a great place to identify browser issues.
You may use these shortcut keys that I've listed below:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox: press Ctrl + Shift + P
- Safari: press Command + Shift + N
Then, log in to your QuickBooks Online account. If it works, go back to your regular browser and clear the cache to delete stored site data and improve the system performance. Also, you can use other supported browsers. It could be that the one you're currently working on has a temporary problem with QuickBooks.
However, if the problem continues to occur, I'd suggest contacting again our QuickBooks Support Team. They have the tools to pull your account to see the cause of the issue.
I'll be here if you need further assistance with troubleshooting. Other questions will also be acknowledged if there are any. Feel free to let me know in this thread. Take care.
