How is MAU counted?
MAU (Monthly Active Users) is the number of unique users (with uniqueness defined by the user-ID) that create or consume content on Social+ servers through SDK or API within a monthly billing cycle. All service requests except authentication* are counted as MAU. MAU number is based on per-user instead of per-device, meaning that a user with the same user-ID with multiple devices will be counted as 1 MAU.
*Authentication service requests are Token, register device, register session.
