not receiving messages on apple watch

Hi

How notifications behave depends on the status of your devices and your settings. With Wrist Detection enabled, in order to bring notifications to your attention as soon as possible:

- If your iPhone is unlocked, you will receive notifications on your iPhone instead of on your watch.

- If your iPhone is locked or asleep and your watch is unlocked (regardless of whether the watch screen is asleep or awake) and on your wrist, you will receive notifications on your watch.

- If your watch is locked or has Do Not Disturb enabled, notifications will go to your iPhone.

Hi,

From the Apple Watch User Guide ...

If you don't see notifications on your Apple Watch

When your Apple Watch locks or you turn on Do Not Disturb, your notifications go to your iPhone instead of your watch.

• You’ll see on your watch face when your Apple Watch locks. If your Apple Watch has a passcode, it locks automatically when you aren't wearing it, when it loses contact with your skin, or while it's charging.
• If Do Not Disturb is on, you'll see on your watch face. To turn this feature on or off, swipe up on the watch face, swipe left or right to the Settings glance, then tap .
