I found this thread https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-6-series/204247/how-to-change-the-colour-of-navigation-course-follow-line-with-your-own-map-theme and tried to do the same with a Epix Pro but can't get it to work.
Is it possible to customize map themes on Epix Pro? Already tried modifing the original themes (I do have backups) and restarting the watch, but when I start a Navigate acitivity with a planned course then it still shows the original theme's purple color instead of the green one that I set in the theme file. What am I missing?
It might be relevant that I'm using Android File Transfer.app on mac.
