AFAIK, this happened after the latest updates were released, as I know that prior to updating it was working fine. I raise my watch up, the clock face appears, I say "Hey Siri"...and, nothing happens. It was always kinda slow and flaky, but, it usually after a few seconds would open up the audio screen where you could see your voice being heard. I've verified that the setting on the iPhone is correct (don't see a Siri setting on the watch itself), and verified that the mike works fine by making telephone calls. Any ideas, or, is this some bug with the newest Watch OS. Thanks!
