QB Online not allowing me to add accountant

Glad you've reached out to us here in the Community space, Nigel. 

I'd be happy to help you resolve the browser issue you're facing while adding your accountant to your QuickBooks Online (QBO) account.

To start, please ensure your internet connection is secure and stable when accessing your QBO account. Then, you can use the Refresh function or click the F5 shortcut keys to refresh your browser's active window. 

On the same note, you can open your account using an incognito or private browser, as cache-induced issues can affect the program's performance and hinder you from accessing QBO to its optimal function. You may use the following shortcut keys:

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

If it works fine using the private browser, open your account using the original browser and clear your browser's cache. You may also try accessing your account using other supported browsers and devices.

For future reference, if you need help managing your user roles and permission, please refer to these articles:

• Learn about usage limits in QuickBooks Online.
• Add and manage users in QuickBooks Online.
• Add and manage custom roles in QuickBooks Online Advanced.

Also, you can remove your accountant if you no longer want them to access your books. 

I hope this information helps you resolve the issue. If you need further assistance, please don't hesitate to reach out to us again. Have a great day ahead and stay safe!
