Hi,
New to Garmin and have used a Windows Mobile with Run Sat who are now closing down. They have provided TCX files for my data which appear to be valid as they import into Strava with no problem.
When I try to drag / drop into Garmin Connect Manual Import I get the error that I have attached in the pic. Restarted pc, tried on Edge & Chrome and no ad blockers. Any ideas really appreciated as I would like to really start using Garmin and the fenix 3.
Thanks,
Rob
