I used my maps on my phone yesterday and of course it opened in my watch. It's almost like it didn't turn off though - my battery was down a lot earlier, and I couldn't remove the maps app from my dock on my watch. It's the last one popping up, but when I swipe it only gives me the option to keep in dock. It makes me worry that it'll run in the background and drain my battery. It is definitely turned off and closed in my phone.
