Latest Apple Watch OS, Latest El Capitan public release (not beta). When I move my wrist and the screen comes on (happens about a dozen times an hour while I type / write), the iMessage icon appears on my dock. When i click the icon iMessage says, "handoff could not be completed" When I move my wrist to turn screen off on apple watch, icon goes away. I've tried restarting my phone and macintosh to no avail. Should I reset my apple watch?
