The Knowledge Base does not support freely switching an existing Hostess account from one Agency to another.
Existing account rule
A Hostess already working on Chamet should not be rebound to another Agency.
Documented account-reset path
The FAQ states that a Host who wants to leave the current Agency must delete the current account and wait 90 days for Face Verification data reset before registering a new account under another Agency.
Important
Account deletion and Face Verification reset are significant actions, so the Hostess should review the implications before proceeding.
