Hi,
Am facing this exact error. I did a long ride over 6 days and when I came back and wanted to sync, it didn't go through. Auto upload didn't work and when I tried to upload the file manually it gave an error that they don't support the file am trying to import.
Would you be kind enough to help fix the attached file and share it back?
This has been the longest and most strenous ride of my life yet and it's so disappointing that am not able to view it.
Many thanks in advance for your help.
