Hi Ziqiao, Thank you for the reply. I am still waiting for a response from Strava. I can see the workouts in both Fitness and Health. I also have a thought that maybe the only workouts that Health allows to be shared are those created by the Apple Workout app. Are you able to confirm what the intent is with syncing? Should Apple Health allow workouts created with 3rd party apps to be synced via Health with other 3rd parties? Thanks
