Update an existing AudienceTarget.

AudienceTargetingCondition specifies conditions for AudienceTargeting.

This condition object contains various filters on multiple dimensions of bid-request, app, and user. Advertisers can selectively configure desired filters to form a meaningful AudienceTarget condition collectively. The configured individual filters must be satisfied unanimously in order for the resulting collective condition to be satisfied.

Only filters with values will be effective. When a filter condition accepts a list of values, i.e., list of countries for "allowed_countries", the filter condition will be met when any match is found among the list.

String literals are case insensitive unless specified otherwise; i.e. "USA" and "usa" equally represents the United States of America.

SharedAudienceTarget represents a persisted AudienceTargetingCondition that can be shared across multiple Campaigns. It can be referenced by ID by other objects, e.g. the Audience object.
