以下哪兩項是金融公司決定宣傳應用程式的常見原因？

Financial companies often use app campaigns to boost user engagement, encouraging existing users to interact more frequently and deeply with the app's features. This could involve checking balances, making payments, or exploring new financial tools. They also aim to help users explore the app, guiding them to discover and utilize the full range of services offered, which can lead to increased adoption of features and higher customer satisfaction. "判斷應用程式使用者是否有偏好的銀行地點" (determining if app users have preferred bank locations) is less of a direct campaign goal and more of a data insight that might inform campaign targeting, but not the primary reason for running the campaign itself. "藉由應用程式吸引消費者致電客服人員" (attracting consumers to call customer service through the app) is generally counterproductive; apps are designed to reduce the need for calls by providing self-service options.
