Activity sharing not working

Hi

The following steps may help, having previously resolved the same issue for some other users (check after each):

Check that you are following the instructions here, including under the heading "Get help with Activity Sharing":

• Share your Activity with your Apple Watch - Apple Support

If you have not yet done so, check that you have each updated to the latest software on both your iPhone and Apple Watch:

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

Unpair and re-pair your Apple Watch (each of you):

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app. Choose to Restore from Backup during set up. Most data and settings will be restored, with some exceptions (eg Apple Pay cards, passcode).
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

If the issue persists, then the following further steps may help:

• Sign out of iCloud on your iPhone:
  • Go to: Settings > [your name] > scroll down and tap on Sign Out.
  • Follow the onscreen instructions regarding your iCloud data.
• Restart your iPhone (normally):

  Restart your iPhone, iPad, or iPod touch - Apple Support

• Return to the previous settings screen and sign back in to iCloud.
• It may help to also restart your Apple Watch (normally) after having followed the previous steps:

  Restart your Apple Watch - Apple Support

If the issue then persists, I suggest that you contact Apple Support or make a Genius Bar reservation for assistance:

• Contact - Official Apple Support
• Apple Support (@AppleSupport) | Twitter
• Genius Bar Reservation and Apple Support Options - Apple
