Notification icon missing on Apple Watch in iOS 11

Question

Notifications coming from our app in iOS 11 are missing the app's icon when they appear on the Apple Watch.

We have the iPhone Notification iOS 7-11 icons in our AppIcon asset, as well as iPad Notifications iOS 7-11, and all of the pertinent spotlight, settings, and app icons for various devices for iOS 7-11.

Any ideas as to what we might be missing? This was working fine in iOS 10 and it stopped working in iOS 11.

Answer 1

As @Skyborg pointed out, this appears to be a watchOS bug and is fixed in watchOS 4.1.
