We have many security features in place on bn.com to detect and prevent misuse and malicious actions on the site. If any of those features are triggered, an error message states "Our system has detected this as an unauthorized action."
If you believe you are receiving this message unnecessarily, try the following steps:
1. Attempt to complete the action using a different browser
2. Clear your browser’s cache and cookies (click here for instructions, if needed)
If neither of these steps resolve the issue, we ask that you wait and try to complete the action at a later time.
