how was it fixed?
Serverside update. The watch (at least mine) has always been able to display turn-by-turn directions as long as they were included in the file. Until recently this has not been the case with routes sent from garmin connect to Fenix 5S, while the same routes sent to other devices like a Forerunner 935 contained turn-by-turn directions.
Ok how do i then include it in the file?
you just have to send a route from garmin connect to your watch and it will contain turn-by-turn directions (unlike old routes you probably already have on your watch)
no it does not work!
You can use the tool https://www.gpxsee.org/ to verify that the files contain waypoints with turn directions. You can find the route files when you connect the watch to your PC via USB and go to "COURSES".
You can also try to create a route on https://www.plotaroute.com/runningrouteplanner,download it as fit-File and copy it into that folder - if this also doesn't work, you're talking about a different problem.
Are these courses created in connect or third party?
