Already received the software update 12.27 however no information of the changes on this forum. I'm not beta user so I received the final version.
Now is possible to select a point in the map and start navigation without crashing and restart the wath.
No, watch still crashes.
It works if there's only one name in the list when you select a point on the map. If there is more than one name it will crash. The workaround is to move the cursor slightly away from where you want to select, so it doesn't find any roads/tracks/POIs to show. The navigation will still work correctly.
