Incoming Message Notifications
Your fitness watch vibrates for an incoming message
when the corresponding notification is displayed in
your phone's status bar. You can view new messages
by swiping up on the screen or flipping your wrist.

You need to enable your phone's notification function in
the status bar, and ensure that the incoming message
notification function is enabled in the app (disabled by
default).
If your fitness watch detects that you are asleep, or Do not
disturb mode is set in the app, your fitness watch will not
vibrate for incoming messages.
