Can AutoPPC change my account without me approving?

No. AutoPPC does not directly change Amazon campaigns in the beta. On paid plans, advertising drafts wait in Review; you approve the rows, download the bulk file and upload it yourself.

The copilot cannot approve its own advertising drafts. It can preview supported AutoPPC configuration changes, but saving them requires your separate explicit confirmation. Changing an AutoPPC schedule is different from applying an advertising change.

Scheduled analysis can run while you are away. That prepares work for your next review; it does not give the copilot permission to change Amazon.
