Nice app... when it works – myChevrolet Review

Very much appreciate the functionality of the Apple Watch interface but, majority of time am met with a red iPhone graphic with a slash thru it and cannot launch the app. No explanation anywhere of what this graphic means or how to solve for it. Five stars if not for this issue. UPDATE: Received a voicemail from customer support that informed me that despite being told under separate correspondence that I must have iPhone software update 10.0 or better along with Apple Watch software 3.0 or better (of which I do)... that in fact the MyChevrolet App is not compatible with Apple Watch. I do not understand! MyChevrolet App is advertised as being compatible and it has worked in the past, changed review to 1 star. Love my Chevy Camaro but customer support, not so much.
