I've noticed that the calories shown in the Garmin Connect app only reflect the calories recorded by my Forerunner 255, which is set as my primary device. If, during the day, I also do a cycling session recorded with my Edge 540 (same account and profile), those calories are not included in the total calorie count. As a result, the app shows a total of, for example, 2000 kcal instead of the 3000-3500 kcal that should be displayed.
