Wear and Bug Fixes
Let's hope these issues ARE fixed, once and for all!
So far so good; I've reinstalled message+ on my phone and the android wear app has been reactivated. I appear to be receiving and sending messages without the need of wifi. The call setup no longer appears as notices nor as an independent app on the watch. I think I'll see how it behaves after a few days at work before I make the final verdict.
