I spoke too soon, google now alerts through your app are now back. Here's the funny part, I unactivated the notifications app, but STILL get google now messages!! I know it's your app because it has the large pixelated weird looking contact picture on there.
I had to uninstall the app, hopefully in the future it will be ready for prime time. Some suggestions:
The listener part, that listens to alerts turns on EVERY single time I get a notification, even if they are blocked. It's very annoying to have to turn this off, I suggest it only run in the background or maybe just once the first t ime you get the alert so you can block it or allow it. Also put in a decent background, the one on there looks horrible, maybe just a plain black background.
Fix the google now weirdness.
Fix the contact picture to not be overblown/magnified like the stock gear app does.
Alerts get truncated very badly. The stock gear app displays an entire page of text, your app only displays the first half dozen words then just cuts the rest off. The usefulness of the gear S is instantly seeing what message or alert you missed, and not having to touch the watch to get the entire message.
