Hey,
I already reported it on the Play Store and got sent here. The issue is, when I start using Navigraph on the outer screen of my Pixel 9 ProFold, everything works fine. As soon as I open it up to switch the the big inner screen, my route will no longer show up on the map. The app is still fully functional, just the rendering of the route on the map is gone. When I open Navigraph while using the inner screen, it works flawless. So the issue is in the switching.
If you need more input, maybe screenshots or something, just let me know
