Apple Watch Activity Ring Notifications

Hi

Whilst I can't say why that is happening, the following steps may help:

If you have not yet done so, also update your iPhone to the latest software:

• Update your Apple Watch - Apple Support

Check that your personal information remains accurate:

• On your iPhone, in the Watch app, go to: My Watch (tab) > Health > Edit - tap and adjust items, then tap on Done.
• If the setting for Wheelchair currently states "Not Set", then change it to "Yes" or "No" as appropriate.

Check your notification settings:

• On your iPhone, in the Watch app, go to: My Watch > Activity > turn on Goal Completions along with any other desired settings.

Check that Wrist Detection is turned on and that, if passcode is enabled, you are unlocking your Apple Watch after placing it on your wrist:

• On your iPhone, in the Watch app, go to: My Watch (tab) > Passcode > turn Wrist Detection on.
• Note that Wrist Detection can be affected by temporary or permanent skin changes, such as by some wrist tattoos.

Check that you are wearing your Apple Watch sufficiently snugly on the top of your wrist (it may otherwise believe that it has been removed):

Close certain apps and restart both your iPhone and your Apple Watch:

• Close the Watch app, Activity app and Health app (if open) on your iPhone:
  • Double-click the Home button, then swipe up on each app preview to close the apps.
• Turn both devices off together, then restart your iPhone first:
  • Restart your iPhone, iPad, or iPod touch - Apple Support

If the issue persists, then it may help to unpair and re-pair your Apple Watch:

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
• Initially choose to Restore from Backup during set up (most data and settings will be restored, with some exceptions, such as Apple Pay cards, passcode).
• If the issue persists, consider instead unpairing and setting it up as a new watch.
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

If the issue persists, then I suggest that you contact Apple Support for assistance:
