Hello! I tried to follow along and repair my own files, but haven't had any luck so far. I wanted to see if anyone could be of any help.
It's a small file, so I'm using all is lost, but I figured I'd ask anyway.
This has happened twice to me now- I start a route, it disapears as if I never started it, I re-start it as I'm riding and the unit performs as usual. Once I save and try to upload the file, it won't upload via the Garmin phone app and when I try to upload it manually to Strava, the ride stops where I re-loaded the route.
