"Pause" in an account's row under "Ad accounts" stops every campaign AdFleet has ever created on that account — not just the latest launch's, Stats duplicates included. The confirmation is explicit: "Stop EVERY campaign AdFleet has ever created on '{account}'? Nothing already run is undone — this only stops it."
- Campaigns created by hand in Ads Manager aren't touched by this button — stop them in Stats or in Ads Manager.
- It's a manual, single-account action, not an auto-rule and not a rollback: what already ran stays as it was, it just stops spending.
- There's no "turn everything back on" — resume what you need in Stats.
- Available to roles that can launch, for the accounts they see. If the account's token is dead or blocked (#200, profile check), the pause can't be sent — stop it in Ads Manager.
