Boeing says optional 737 MAX alert was 'not activated as intended'

Boeing Co said an alert for angle-of-attack (AOA) sensors on its 737 MAX jets was "not activated as intended" for some customers, responding to reports it failed to tell Southwest Airlines Co and the U.S regulator that the optional feature was deactivated before a crash in Indonesia in October.
