If your heart minutes are not syncing follow these troubleshooting steps.
In the Galvan app go to More -> under resources tap on Help with Syncing and make sure you have the correct device linked and phone permissions are all enabled correctly to receive physical activity information.
Apple and Google health kits will now need you to start your workout on your watch to get more accurate heart rate and workout data. If you do not set a workout on your watch you run the risk of the workout not being recorded to the Galvan app and receiving no heart minutes.
