very good on iPhone 7, poor on Watch Series 2

I like this app on my iPhone, but when I tried using it on the Apple Watch (series 2), I noticed that the origin was displayed on the Watch face, and there was a significant delay with the update to indicate the next maneuver...

When using only the Watch (but connected to iPhone that was sitting on the passenger seat) I missed a number of turns due to poor update frequency...

Also, the App would "disappear" on the Watch, requiring several clicks to the Digital Crown, followed by manual maneuvering to the Sygic Icon, and relaunching the app, and waiting for communication update (which again showed the origination address and not the next turn)...

So, iPhone great!
Apple Watch... find something else!

When comparing the Watch App to the iPhone App, even when the iPhone was working great, the Watch was still seen to fall behind...
