Hi there, @Abdul Rehman.
I appreciate you for sharing your concern here in the Community. I can see that you've been experiencing this issue for the last two weeks. I'd suggest you perform the basic troubleshooting steps first by using an incognito again to see if it work. Here's how:
- Open a default browser, then follow these shortcut keys to open a private or an incognito window:
- Chrome simply press Ctrl + Shift + N.
- Mozilla Firefox and Internet Explorer, press Ctrl + Shift + P.
- Safari, press Command + Shift + N. Make sure you're using the latest version.
2. Log in to your QuickBooks Online.
3. Re-create the user.
If that works, follow the steps to clear the browser cache in the help article: Delete or disable cache and temporary internet files in your web browser.
If you're still experiencing the same issue, I'd recommend contacting our Customer Care team. They can help you check the error and perform an escalation whenever needed for you to resolve the issue.
Feel free to message us again if you have more questions. We're always around to help.
