Had a tour scheduled with roughly 102 km.
After the first 35km I stopped shortly to change my jacket and paused the activity. 2 minutes later I wanted to resume.... but after looking at the edge screen I was back to the normal starting screen. No activity has been saved, nothing.
Thinking this was just a visual bug I continued with a new activity. Back at home it got confirmed: the edge simply cancelled the first activity without any notification as if it never happened.
Save to say I am a bit annoyed by that.
With various recovery tools I found 4 .tmp files from the corresponding time but not .fit file. C9E73426.tmp seems to be the correct tmp file.
