Expected behavior: When Do Not Disturb is enabled on the phone, notifications should be suppressed on the watch. This is the case when using a Garmin watch with iOS.
Observed behavior: When Do Not Disturb is enabled on an Android phone (Google Pixel 9 Pro in my case), phone notifications are still shown on the watch. Enabling Do Not Disturb on the watch itself is not a workaround, as the phone's DND settings can be configured to allow certain notifications, while DND on the watch blocks all notifications.
This is a bug, not a feature request, as the behavior is inconsistent between iOS and Android.
