Every change made at the campaign, ad set or ad level passes through a series of safety checks before being sent to Meta. These checks are designed to prevent changes made in autonomous or semi-autonomous mode from causing unexpected or excessive spend — see Autonomous Actions.

The campaign → ad set → ad chain you create opens in Meta in a paused state by default; going live requires a separate approval step. If any check fails, the change is not sent to Meta and drops into the approval queue.
