Why can't the Redmi Watch 5 Active receive message notifications?

Please confirm whether the message notification in the APP is turned on, and whether the sync notification is turned on or the switch of the corresponding APP is turned on. If it is turned off, the watch cannot receive the message.
Please confirm whether the Mi Fitness APP has sufficient permissions, including the permission to get notifications and the permission to run in the background, to ensure that the APP can push notifications to the watch in the background.
Please check if the watch is in any of the following modes:
1. Whether to turn on Do Not Disturb mode;
2. Whether to turn on Do Not Disturb synchronization and turn on the mode on the phone;
3. Whether to turn on sleep mode;
4. Whether the watch is not being worn, and the reminder switch is set to notify only when worn.
Any of the above states will not remind the watch when the message is notified.
When the watch is connected to the iOS phone, if the phone cannot receive the message reminders, please refer to the following to check:
1. Ensure that the phone’s Bluetooth is connected to the device;
2. If connection issues persist, ignore the device in Bluetooth settings, then enter the Mi Fitness APP to re-pair the device;
3. If Bluetooth is connected, tap the small icon next to the connected device in Bluetooth settings to access the watch's Bluetooth details page. Confirm that the sharing system notification is open.
