Configurable elements include:
+*   **Maintenance Mode:** Instantly enable or disable maintenance mode for the mobile app, displaying a custom message to users.
+*   **Force Update:** Mandate app updates to a specific version (`latestAppVersion`), with an option to force users to update (`isLatestVersionOnly`). Configurable update URLs for iOS and Android are also available.
+*   **Ad Settings:** Comprehensive control over advertising strategy:
+    *   **Global Ad Enablement:** A master switch to enable or disable all ads.
+    *   **Primary Ad Platform:** Choose between `AdMob` or `Local` ad platforms.
+    *   **Ad Unit Identifiers:** Configure specific ad unit IDs for each platform, including `feedNativeAdId`, `feedBannerAdId`, `feedToArticleInterstitialAdId`, `inArticleNativeAdId`, and `inArticleBannerAdId`.
+    *   **Feed Ad Configuration:** Define ad types (`native`, `banner`) and frequency (`adFrequency`, `adPlacementInterval`) based on user roles (`guestUser`, `standardUser`, `premiumUser`).
+    *   **Article Ad Configuration:** Control in-article ad enablement, preferred `bannerAdShape` (`square`, `rectangle`), and specific `inArticleAdSlotConfigurations` (`aboveArticleContinueReadingButton`, `belowArticleContinueReadingButton`).
+    *   **Interstitial Ad Configuration:** Manage global interstitial ad enablement and frequency (`transitionsBeforeShowingInterstitialAds`) for page transitions, also tiered by user role.
+*   **Feed Decorators:** Manage the enablement and visibility of various in-feed promotional and engagement elements, such as `linkAccount`, `upgrade`, `rateApp`, `enableNotifications`, `suggestedTopics`, and `suggestedSources`. Each decorator can be configured for specific user roles and `daysBetweenViews`.
+*   **User Preference Limits:** Set maximum limits for followed items (countries, sources, topics) and saved headlines, tiered by user roles (`guestUser`, `standardUser`, `premiumUser`).
+> **Your Advantage:** Gain dynamic control over your mobile application's behavior and monetization strategy. Adjust critical settings on the fly, ensuring your users always have the best experience and your business goals are met without the overhead of app store releases. 🚀
