Bad sync of calender
I have a apple watch series 1 iOS 4.3.2 and a iPhone X iOS 12.1.2. Recently I have noticed that not all of my appointments show up on my watch. All of my appointments are in the same calender in my phone (I have several calenders that do not need to be seen on my watch). Any suggestion short of reinstalling each device's iOS? If it had been all appointments it would have been easier to understand but random appointments....?
