Change notification settings on Apple Watch Ultra
By default, the notification settings for the apps on an Apple Watch Ultra that you set up for yourself mirror the settings on your iPhone. But you can customize how some apps display notifications.
Choose how apps send notifications
Open the Apple Watch app on your iPhone.
Tap My Watch, then tap Notifications.
Tap the app (for example, Messages), tap Custom, then choose an option. Options may include:
Allow Notifications: The app displays notifications in Notification Center.
Send to Notification Center: Notifications are sent directly to Notification Center without your Apple Watch Ultra making a sound or displaying the notification.
Notifications Off: The app sends no notifications.
Notification grouping: Choose how notifications for the app are grouped. Options include:
Off: Notifications aren’t grouped.
Automatically: Your Apple Watch Ultra uses information from the app to create separate groups. For example, News notifications are grouped by the channels you follow—CNN, Washington Post, and People.
By App: All the app’s notifications are grouped.
Tip: Some apps let you choose the specific kind of notifications you receive. For example, for Calendar, you can allow notifications only for certain things, like when you get an invitation or someone changes a shared calendar. For Mail, you can choose which email accounts are allowed to send notifications.

To have the app once again notify you immediately, open the Settings app on your iPhone, tap Notifications, tap the app, then tap Immediate Delivery.
Turn off Time Sensitive: Time-sensitive notifications are always delivered immediately, even if you’re using a Focus that delays most notifications. However, if you want to prevent this app from delivering even time-sensitive notifications immediately, tap this option.
Turn off: The app sends no notifications. To reenable notifications from the app, open the Apple Watch app on your iPhone, tap My Watch, tap Notifications, tap the app you want to adjust, then tap Allow Notifications.

Tap to Show Full Notification: When you raise your wrist to see a notification, you see a quick summary, then full details a few seconds later. For example, when a message arrives, you see who it’s from first, then the message appears. Turn on this option to stop the full notification from appearing unless you tap it.
Show Notifications on Wrist Down: By default, notifications don’t appear on your Apple Watch Ultra when your wrist is down. Turn on this option to make notifications appear, even when your Apple Watch Ultra is turned away from you.
