I have a watch worktout app and I was excited to learn that haptic feedback now works in the background. However, when I tried the feature in beta 1 of watchOS 3 it doesn't work for me. I have WKBackgroundModes in my plist of the watch extension and it has a single arrary entry value of workout-processing. I also have a custom countdown timer and it run fine in the background, but the haptic feedback only work if if the app is active. Every 10 seconds I play a haptic using the following:
WKInterfaceDevice.current().play(.notification)
Is this a known issue?
