Today I tested again the plugin:
recording and guide activated on the phone
the watch as a simple viewer
I found on the watch the Navigation watchface, why is it activated ? I have the guidance on the phone and not the navigation, I was following a track I did with locus planner.
Today it worked perfectly.
I'm still waiting for the custom watchfaces, than it'd be perfect for my use case, long distance running/trailrunning.
