it sounds wierd to me, as I read the official FAQ and it says:
"Our Ride Sync feature allows you to automatically upload all completed TR workouts to your Garmin Connect account, and automatically adds all completed Garmin Connect workouts to TrainerRoad
Once Garmin Connect is connected, all your future completed rides will automatically sync to both accounts."
anyway it’s not a big issue itself, but it’s confusing and a timeloss for writing all of this.
