Why doesn’t the Xiaomi Watch S4 receive notifications from the phone?

When the Mi Fitness APP maintains a Bluetooth connection with your Xiaomi Watch S4, it pushes notifications from the phone’s notification bar to the watch, notifying you of new notifications on the phone. However, if there are no notifications displayed in the phone's notification bar, the watch will not receive any notifications, even if the phone's APPs have new notifications.
If you find that you're not receiving notifications, please follow these steps to troubleshoot:
1. Ensure that the phone has a stable network connection, Bluetooth is enabled, and the phone is properly connected to the watch;
2. Make sure that notifications are set to display in the phone's notification shade;
3. Check if the APP notification option is enabled in the Mi Fitness APP;
4. Verify whether the watch is in Do Not Disturb or Sleep mode. During these periods, the watch will not vibrate to alert you of new notifications;
5. Check if the wearable only is enabled on the watch. With this switch turned on, the watch will only receive notifications while being worn;
6. If your phone is running on the Android system, it is recommended to enable background running permissions to ensure that the APP operates properly in the background.
