Instagram notifications may stop working due to disabled in-app notification settings, restricted device permissions, battery optimization features, outdated app versions, or network connectivity problems. Both Android and iOS systems can limit background activity, preventing timely alerts, while users may also unknowingly mute notifications for specific activities like messages or posts. Resolving the issue typically involves checking Instagram’s notification settings, enabling system-level permissions, disabling power-saving restrictions, updating the app, and ensuring stable internet connectivity.
