I've build a watchface for my fenix3 which runs OK in de sdk simulator, but when I copy the .prg to my device, it's shows a blank (white) screen. After a few seconds it will show the default digital watchface (fallback option?). The app is pretty much a copy of another watchface which runs fine (GF3240: https://apps.garmin.com/en-US/apps/f5d277e2-0ff3-45f2-9f83-8f398ff71f88).
Has anyone else run into this problem? Or is there a way to debug this?
Note: all the firmware versions are up-to-date; watchface is build with sdk 1.1.1 on OSX
