A repeated disconnect needs the actual failure reason, not more pairing attempts. Check whether WhatsApp removed the linked device, whether the number reports a connection error, and whether Polymorfa refused a restart for funding or access.
Record two or three relevant times and the visible statuses, then contact support. Mention recent phone, linked-device, or integration changes. Pause repeated automated restarts while the failure is investigated. Do not send authentication files or repeatedly delete and recreate the number; those actions can remove useful context without solving the cause.
