Reason: You may have too many unread messages. The watch can receive a maximum of 20 message notifications. If there are more than 20, the newly received message will overwrite a previous message.
Solution: Please check message notifications on your watch promptly; if you find that an unread message is lost, check it on your phone.
- Only messages displayed in the notification bar of your phone are received on the watch.
- You will not be notified on the watch again of messages already read on your phone.
