Google Ads API v23 released with PMax channel breakdowns, granular invoices and campaign date-times

v23, the first release of the monthly cadence, enabled ad_network_type breakdowns for Performance Max, granular campaign-level invoice details via InvoiceService, Campaign.start_date_time/end_date_time replacing date-only fields, store location details in PerStoreView, a LIFE_EVENT_USER_INTEREST audience insights dimension, AudienceInsightsService.GenerateAudienceDefinition (natural language to audience attributes) and new competitive and conversion-date metrics in ShoppingPerformanceView.

v23 also removed the ability to create shared ads and blocked creation of new call-only ads, per earlier deprecation announcements. v23 sunset: February 2027.
