I did a triathlon on Saturday using auto transitions for the first time. After the race it didn't upload to Garmin. Since then I've done another activity which uploaded successfully
I tried connecting to my PC and Garmin Express, got the file and tried to manually upload, but Garmin states the file is corrupt.
I'm not sure what can be done to fix it, apart from recommendations to use the Fit File Repair Tool which I don't have access to
The file is here in zip https://drive.google.com/file/d/1bsESoo-2hr6lIsee8Z8tzPwDVBwbY-Tn/view?usp=sharing and here in FIT https://drive.google.com/file/d/11q_M8Z1Zkzr9NbQU9UShXW7JaGmBSHO9/view?usp=sharing
