No notification in ultra watch when phone is turned off

Hi there subhadip97,

We can help. Is your Apple Watch locked when you don't receive notifications? If so, this is expected:

If your iPhone is locked or asleep, you get notifications on your Apple Watch, unless your Apple Watch is locked.

If you're not receiving notifications as expected when your Apple Watch is unlocked, check to be sure you have notifications for those apps turned on with these steps:

Customize your Apple Watch notification settings

1. Open the Apple Watch app on your iPhone, then tap the My Watch tab. 

2. Tap Notifications. 

3. Tap an app to see its options. To use the same notification settings on apps that appear on both your Apple Watch and iPhone, tap Mirror my iPhone. Some apps allow you to customize your notifications. Tap Custom, then choose an option:

- Allow Notifications: Notifications appear in Notification Center and your Apple Watch alerts you. 

- Send to Notification Center: Notifications are sent directly to Notification Center without your Apple Watch alerting you.

- Notifications Off: The app sends no notifications.

4. If you customize an app's notifications, you can also group notifications from that app. Tap Notification grouping, then choose an option: Off, Automatically, or By App.

Some apps offer further customization, while others only let you turn off Apple Watch notifications completely. Scroll down to the Mirror iPhone Alerts From section and turn off the setting next to the app.

Take care.
