Does anybody know how to overcome the known bug of not be able to add an accountant? I tried with 2 browesers

Let me chime in and help you add an accountant to your account, @bullfas-gmail-co.

Let's perform some steps to help us check what's causing the issue why the accounting firm section is missing. 

First, ensure that you're logged in as the Master Admin. Adding an accountant in QuickBooks Online (QBO) needs admin rights. 

Second, a possible browser issue might be cause of this. There are times that the webpage is full of frequently accessed page resources, thus causing some errors or unusual responses. To fix this, access your account using a private browser. 

You can use either of these shortcut keys:

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

You may also need to clear your regular browser's cache or delete temporary internet files. That'll remove previously stored data that might have caused the issue and prevent any unexpected behavior. 

I'm also attaching this link to help you add an accountant. This way, they can review your books, make corrections, and fix any tricky transactions. 

Feel free to get back to this thread if you need clarifications about inviting an accountant to your account. I'll be happy to lend a hand again. Stay safe and enjoy the rest of the day.
