Found a similar post for Fenix 5(https://forums.garmin.com/forum/on-the-trail/wrist-worn/fenix-5x/1447580-unable-to-navigate), but it describes exactly what I'm experiencing on my Edge 1030 right now.
Device: Edge 1030
Firmware: latest 7.0
REPRO (This has been my consistent flow since forever):
1. Create course in Strava
2. Export Strava GPX file to computer
3. Move file to NewFiles folder on device
4. When device starts, find saved course and choose "Ride"
EXPECTED: It starts the course, provides prompts on turns, and Dist. to Next field is correct.
ACTUAL: It provides first turn instruction and then stays there on map screen. Dist. to Next field is always either 0m or 9m.
