Reporting a bug. Yesterday I recorded a 9 hour walk which I was navigating using a course I had created in Basecamp. I saved this activity and I can see it on the watch in history and can see the stats etc.
I tried first to transfer the activity to Basecamp on my PC. The activity did not transfer. I then tried to sync on WiFi, then Garmin Express on PC and then via Garmin connect on my iPhone.
Each time it failed either by not completing or with a message. On WiFi the message was that 1 file had not transferred. (Or words to that effect)
I accessed the watch via windows explorer and found the activity as a FIT file in the folder \Internal Storage\GARMIN\Activity\PendingHD. I copied this to my PC and deleted it from the watch.
I was then able to manually import it to Garmin connect on my PC and to Basecamp. The track appears complete with no real issues I can see. No random jumps off track. However in Garmin connect, on PC, it displays some strange icons which I do not understand.
Watch is on latest firmware. I have climbpro enabled.
Previous activities worked fine so far.
Any advice appreciated.
