Sleep mode not working after update

Hi JoLana49,

Thanks for posting in Apple Support Communities! To update your sleep schedule on your Apple Watch, follow the guidance below from the article Track your sleep on Apple Watch and use Sleep on iPhone:

1. "Open the Sleep app and tap Full Schedule.
2. Tap the schedule you ant to edit.
3. Tap the days under Active On, then tap the days you want to set the sleep schedule for.
4. Tap Done to save your changes. 
5. Tap Wake Up or Bedtime.
6. Tap the hour or minute and turn the Digital Crown to adjust the time. Then tap the checkmark to save.
7. Tap Alarm to turn on an alarm and adjust the sound and haptics of your alarm.
8. Tap Edit Schedule in the upper left to save your changes for the full schedule.

You can also turn off your full schedule as needed. In the Sleep app, tap Full Schedule, then tap Sleep Schedule to turn your sleep schedule off or on."

If you're unable to update it with the steps above, we suggest restarting both devices. Restarting can fix many issues. Should it continue, contact Apple Support for further assistance: Apple Support.

Cheers!

Hello JoLana49,

According to the following: Track your sleep on Apple Watch and use Sleep on iPhone

Sleep is not available with Family Setup.

Which means, that you'd need to have this Apple Watch paired to your own iPhone and not someone else's iPhone in the family. In case the Apple Watch is paired to your own iPhone, then it would be best to contact Apple Support They'll need to take it from here.

Wishing you well, take care.
