Hi,
I hope somebody might be able to help me. I did my biggest ever cycling event at the weekend and it tested my Edge 820's battery life to the limit. I activated battery saving when prompted and was able to stop the activity at the end of the ride (10.5hrs elapsed time) but I think it might have corrupted the file while saving. The activity shows in history as a headline (213km) but won't open, and won't sync either through the connected app or by manually copying the file and uploading it. I've tried connect and strava to no avail. I've seen other threads where it's been possible to fix the file so it uploads and I'd be really grateful if it that's possible with this one.

Many thanks
