A support conversation does not automatically grant access to all WhatsApp content. Polymorfa does not retain real message history by default, and a support code is a reference you choose to share, not permission to read a phone or recover unretained messages.
Start with the error, time, and resource reference. Support can ask for relevant reviewed evidence if needed. Share only the portion necessary to explain the incident and remove unrelated customer information. If an investigation involves retained content, access still depends on the applicable authorization and storage rules.
