Hello,
I tried searching these forums, but the searches didn't work at all, so I apologize for any unnecessary reposting on this topic.
Using Garmin Connect Mobile 3.8.2 on iOS 9.3.3 iPhone SE, I'm finding that the active calories on the main screen is short of the calories burned during an activite. See attached screen shots. The running event used a HR monitor and the epix v. 3.20.
Thank you for your time.
Cheers,
Steve
