I just got the Apple Watch Series 2 42mm running Watch 3.1 with Voice Over. I've taken a few calls with it with no problem but on 3 occasions it has irretrieveably crashed. Voice Over went completely silent and couldn't be turned on either using the Crown or the iPhone Watch App. On one occasion it made very alarming squawking noises. The only way the fix it was to get someone to turn it off and it worked normally when switched back on. Has anyone experienced anything like this?
