I will ask something after saying, "Hey Siri" Siri will come on, listen, what I ask will show on the screen, and then nothing. It will just sit there. If I say more, it will also show on the screen. I minute ago I asked, "How many hours from 5 AM to 9:30 PM?" to see what Siri would do. It showed that on the screen I waited about 45 seconds and still nothing and it then showed on the screen my next words, "what the f#$% are you doing". This isn't the only time it's done this. Anyone else? How can you tell Siri that you're done talking? On the iPhone you can hit that invisible button at the bottom. If you press the crown on the watch, it exits. Any tips?
