First time experiencing this. Whilst I retrieved the .fit file and it uploaded well to Strava, MapMyRun with HR and Cadence showing well, for Garmin it gives 'One of your files was not accepted by the system. Please contact Support for assistance.' If I convert from .fit file and upload say from Strava, it just shows one time not the lap split.
seilogramp and suggestion?
I tried the previous portal responses and didn't come alright. That was a morning run. For the afternoon run, it uploaded well.
