Hello loulou, we apologize that this experience has been less than ideal. Due to a GPS communication problem between your watch and phone, you cannot check your real-time location or track your fitness workouts, including health statistics when the device's are connected. The issue will be resolved with an upcoming software update for your watch and the Galaxy Wearable app. Continue to regularly check for software and app updates for your watch. Until the software is available, disconnect the watch from your phone and use the watch's built-in GPS function. ^Elizabeth
