Not sure if this is a bug or not. It is certainly annoying.
If I have a break in the middle of an activity and wants to charge my watch during this break, Garmin Express syncs the activity that is set to "resume later". I end up having two activities, and have to merge them later.
I would like to sync all other actitivies, but not the one that is active. How do I do this?
Edit: Could "Continue last activity" on the watch be an alternative?
