I'm having an issue where I can import a TCX file but can't export it to TCX again, it gives me an error every time.
I import a TCX file from Endomondo that includes <Cadence> </Cadence> tags for walking running. Endomondo has a steps/minute cadence for walking/running on their pro app.
If I try and export the file from your Garmin Connect website after importing then it will error and say website is undergoing maintenance.
It seems from reading the TCX schema that it is ok to use cadence but your website doesn't handle it properly. Would you be able to either strip the cadence information from the file upon import or even better would be if you could display and be able to export this information again.
Let me know if you need me to send you TCX files for testing.
