Route line disappears on smartwatch
Path line disappears on Galaxy Watch using Android Wear OS and Gear S3 smartwatch using Tizen OS
When the map is zoomed in and out by pressing the top zoom button, the route line is visible again, but disappears again after a while.
This phenomenon is old and has not been improved yet. Since Tizen smartwatches are no longer being made, I hope it will be improved in smartwatches using Wear OS.
