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.
• More information: Notifications on your Apple Watch - Apple Support

If notifications are not being delivered to your Apple Watch as expected, then it may help to follow these steps:

If you have not yet done so, update your iPhone and Apple Watch to the latest software, starting with your iPhone:

• Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support
• Update the software on your Apple Watch - Apple Support

Install any available update for WhatsApp Messenger:

• On your iPhone, open the App Store app > Updates (tab).

On your iPhone, go to: Settings > Notifications > WhatsApp Messenger:

• Check that Allow Notifications is enabled.
• Check that Show in Notification Centre is enabled.
• Check that Show on Lock Screen is enabled.
• If desired, also enable Sounds and Badge App Icon.

With those settings enabled, to configure your Apple Watch to mirror notification alerts from WhatsApp Messenger:

• On your iPhone, in the Watch app, go to: My Watch (tab) > Notifications > scroll down to the list of apps > turn on the button next to WhatsApp Messenger.
