I have the watch set to silent mode, so that I only get taptic notifications for alerts. This works fine for all the built-in apps: messages, reminders, calendar, activity, etc. However, I don't seem to get taptic notifications for third-party apps, like the New York Times breaking news alerts. These appear on the Watch, but only as the red dot on the watch face. I don't seem to get a taptic notification when they come in. What setting controls this, if any?
