I have a couple of questions for those who already have the watch. 1. As stupid as it sounds, how do you switch off the watch? I press and hold the button, then I've tried tapping the power off option, but it doesn't switch off. I've even force pressed the option, but that didn't work. I had to leave it switched on over night. 2. I've got my iPhone on silent. Now that I have my Watch, it's now stopped vibrating to alert me and nothing comes up on my Watch. The only way I know that I have an alert is by looking at the lock screen on my iPhone. Can anyone help please? Thank you in advance.
