Thank you for bringing this to our attention, posunkoyuliia. Let me share some insights on how to resolve the error you've encountered in QBO.

Browser instability and data overload are common causes of outdated windows and partially loaded pages.

To determine if this issue is related to your browser, let's follow some troubleshooting steps to bypass the error:

1. Refresh the current page (Ctrl + R for Windows or Command + R)
2. Sign out to your QuickBooks Online (QBO) account, then sign back in.
3. Try using a different supported browsers.
4. Use a private or incognito window:
   • Google Chrome: Ctrl + Shift + N
   • Mozilla Firefox: Ctrl + Shift + P
   • Microsoft Edge: Ctrl + Shift + N
   • Safari: Command + Shift + N

Once done, sign back into your account and check if you can already add new client subscription as expected.

If the issue persists, I recommend reaching to our Live Support team. They have the tools to securely access your account and thoroughly investigate this unusual behaviour.
