Are they somewhere else and I just haven't spotted them?
How do I know which segments an activity crossed?
Open the Garmin Connect Mobile app (not the web version!), go to Menu » Training » Segments, click the triple dot up right, and check whether Garmin segments are enabled
Thank you. I recently joined strava, and it was using strava segments instead of garmin. I've changed back to garmin and they are back. Thanks.
