Non-breaking backend changes let the Google Ads API attribute some expired GCLIDs and pre-conversion clicks (fewer EXPIRED_EVENT and CONVERSION_PRECEDES_EVENT errors) and relaxed authorization so manager or client accounts can import on behalf of other trafficking accounts (fewer UNAUTHORIZED_CUSTOMER and INVALID_CUSTOMER_FOR_CLICK errors).
