Use the QR code from the current pairing attempt and scan it through WhatsApp's linked-device screen. An expired code, interrupted attempt, or a different account's code can leave the number unconnected. Never send the QR code to support.
Check the Console's resulting status rather than assuming the scan completed pairing. If it fails, record the visible error and time, including whether WhatsApp accepted the scan. Review any funding or access message before trying again. Repeated scans do not bypass a blocked start or a WhatsApp restriction.
