No longer works after upgrade to iPhone 6s

I was using this app on my iPhone 5 with my 2015 4Runner and had no problems. After upgrading to an iPhone 6s only the Bluetooth phone features work. None of the other apps recognize that Entune is running at all. Toyota has been no help. They say "we havent tested the iPhone 6". What kind of customer support is that?
