Google Analytics отображает данные только для 1 пользователя

Я пытаюсь создать страницу, на которой будут отображаться данные об учетной записи пользователя GA. В настоящее время отображаются данные только 1 пользователя независимо от того, кто вошел в систему. Я не понимаю, почему это так, потому что я использую идентификатор клиента для аутентификации вместе с oauth2.0. Я вызываю getFirstprofileId, однако независимо от того, кто вошел в Google, результат всегда возвращает один и тот же идентификатор
