Support cannot substitute for the phone owner's WhatsApp authorization or recover a WhatsApp account on their behalf. If a new pairing is required, the authorized owner must complete it. A Polymorfa support code does not grant access to that phone account.
Recover control through WhatsApp's own account process and review linked devices if the phone was lost or compromised. For a remote owner, use an authorized QuickLink rather than sharing your Console session. Tell support about the connection state you need help understanding, without sending registration or pairing codes.
