Hi - just noticed that for one of my connected friends in Garmin Connect, the info about his activities will show BOTH the Edge 530 used for recording AND that a speed sensor was used, see below screen shot from an actual ride as I see it through the News section in Connect. I NEVER see that for my own activities, even if always also using a speed sensor for tracking the activity.
What is the difference? Would it indicate an issue with speed sensor not working correctly?
