From the perspective of a part-tme dev:0) All of the below have been reported by multiple users in this forum...1) With watchOS 2...BETA 2...2) Restarts periodically, BETA 1 was ok.3) Battery drains very quickly, BETA 1 was ok.4) Haptic Feedback is broke, BETA 1 was ok.5) Erratic paring issues during setup, required restart, BETA 1 was ok.6) Several apps don't start, BETA 1 was ok.7) iMessage is erratic, non working most of the time, locked up a couple times when receiving IMessage.I knew what I was getting into, but I am surprised at some of these...Fortuntately I imagine the devs at Apple are experiencing the same, so I bet the next week or two or three will move us in the right direction with improvements.
