Received my new SS 42 series 2 yesterday and restored it from my series 0 backup. It's generally working well but I've noticed that sometimes it doesn't make a sound or haptic for new emails. At first I thought that it might be the iPhone not receiving the email but, when I look at the watch, the little red notification dot is there and so is the email notification. The majority of new email notifications are accompanied by the 'ding' and the haptic feedback - it's just one or two that are 'silent'. I don't think it can be a hardware issue so I'm assuming a watchOS 3.0 bug. Anybody else had anything similar?
