Important Notes
- AI does not restart — unassigning a thread does not reactivate the AI agent or drip messages. The thread remains in a completed state.
- Admin visibility — once unassigned, the thread is no longer visible to non-admin users (since they only see threads assigned to them).
- Re-assignment — you can assign the thread to a different user by calling the Assign Thread endpoint again.
