Hi to everybody! do you have a problem with registration of new users? it looks like a global problem for all users.

We appreciate you for bringing this up in the Community, @pkopyl-hdlogisti.

Currently, there is no ongoing investigation regarding issues with registering new users. Did you encounter any error messages when attempting to add or invite new users? Providing more details will help us assist you better.

In the meantime, let's perform troubleshooting steps. The problem is likely related to your browser's cache. You can rule this out by using a private or incognito window.

Here are the shortcut keys:

• For Mozilla Firefox browser: Ctrl + Shift + P
• For Google Chrome browser: Ctrl + Shift + N
• For Safari browser: Command + Shift + N

Next, log in to your QuickBooks Online (QBO) account and do your task again. If it works, clear your browser's cache to remove the webpage data causing the issue. If a private browser doesn't work, use other installed supported browsers as an alternative.

Additionally, I suggest checking the FAQs section of this article for guidance on resolving common issues when adding or inviting users: Add and manage users in QuickBooks Online.
