I'm reaching out regarding an issue we've encountered with the QR code functionality in the configuration system. It seems that the code is invalid, and we're unable to proceed with the setup.

Could you please provide insights on troubleshooting steps or any potential updates we might need? Additionally, if there's any specific documentation or support resources related to this issue, that would be incredibly helpful. Looking forward to your quick response!
