Notification indicator not showing on Apple Watch (red dot) also nothing showing in the Notification Centre on Apple Watch

I would encourage you to also submit feedback to Apple so they work on resolving it for a future update: Feedback - Watch - Apple FWIW My series 7 works on notifications

From the Support link: Notifications on your Apple Watch - Apple Support

If you don't see notifications on your Apple Watch

When your devices disconnect, your notifications go to your iPhone instead of your Apple Watch. To check your connection in Control Center, press the side button (for watchOS 9 or earlier, touch and hold the bottom of the screen, then swipe up). If your devices are disconnected, you might see the red iPhone icon , the red X icon , or the Wi-Fi icon . Try to connect your iPhone and Apple Watch.

When your Apple Watch locks or you turn on Do Not Disturb, your notifications go to your iPhone:

• When your Apple Watch is locked, the lock icon  appears on the watch face.
• When Do Not Disturb is on, the Do Not Disturb icon  appears on the watch face. To turn this feature off, swipe up on the watch face, then tap the Do Not Disturb button .

For third-party apps, notifications are delivered only if your paired iPhone is also connected to a network

Not 100% sure this is a fix yet. We did notice that upon upgrade to IOS 17, the default texttone value in the iPhone settings for Messages was set to "None" (not by us, it happened as part of the upgrade).

We have also noticed a significant lag between the time the iPhone receives the message and the time the iWatch displays a notification (e.g., 45+ seconds).

I tried more of the suggestion and none of the standard things work.

Restarting watch fails to fix

Restarting phone fails to fix

Unpairing and restoring phone fails to fix

It is not a focus settings issue

It is not a notifications settings issue

It is not because the phone is in use

etc.

Basically Apple provided a defective update, and as usual, refuses to acknowledge it.

As such, the watch is practically useless and a pain since the notifications are silenced on the phone since the phone thinks the watch is making them, which it is not. This is not the only issue either. The options seletced on my watch face are not matching those set on the phone and are not always being displayed either (but are acted upon with screen touch).

Time to turn off the watch.

Hi I am facing the same problem since I updated to iOS 10. I get notifications for activity completion but not for other apps like WhatsApp.

The watch vibrates so I know there’s a notification on the phone but the red dot doesn’t show on the watch.

how can I fix this? I tried all of the above but it’s not working.

Same here, switched to iphone 15pro and my Apple watch 7, after upgrading to ios10 mirrors only the fitness notifications, check my notifications settings, each app separate notification settings but doesn’t work, Is there any known fix Apple?

Cheers

That solution didn't work on my (wife's) device either.

The phone thinks all is well and doesn't make a sound as it thinks the watch will but the watch fails to make a tone nor display the red icon.

The Notification Center trick did NOT work for me.

Boy, is my wife upset.

Same issue. Nothing fixes it. Two handed use of the watch defeats the purpose. It needs to be fixed.
