Well... I have never really gotten the calendar to work well with Apple Watch. This is one of the more important things I was looking for... having my appointments up to date, on my wrist with reminders, etc. Well, with Watch OS2 it appears to have gone from bad to worse! In earlier OS, appointments would not consistently update, would not sync correctly, etc. You had to toggle the switch to "private" in order to get it to show... rendering it pretty much useless. Now in WatchOS2, NONE of my calendar appointments are showing on my watch. Zero. I have tried everything. I have reset everything. Rebooted everything 20 times. Repaired. and I notice "Reset Sync Data" does not even work in the app. Anyone else having these challenges with calendar??? ugh.
