If a relative has passed away, and you do not see the option to update their living status on their profile, it is likely that your relative has claimed their profile with their email address. You may report the profile as deceased. Once it is reported, birthday and anniversary reminders for your relative will be disabled.
Customer service will resolve the report by unclaiming the profile and updating the living status of the profile to deceased. Once the report is resolved, you and your family will be able to edit your relative’s profile.
