I have a Fenix 5X Plus and Connect synchronizes with Apple Health. Usually I don't really care about the Apple Health data, but, I've always assumed that it would accurately pull from Garmin correctly. I looked today at my Active and Resting Calorie numbers in Apple Health (Garmin is the ONLY source for the data), and,they are WAY off what Garmin is showing me on the website and my watch. Actually, it seems like my Resting Calories just stopped synchronizing completely since November 5th only to start again today. But Active Calories are WAY off too in the past 10 days. I can't think of anything that I did to cause this, but, curious if anyone else is having the same problem. For example, my Garmin is telling me that I burned 1209 active calories yesterday, but, Apple Health only shows 449. 10 days ago (and previously for at least a couple of weeks), Apple Health and Garmin match perfectly.
