So I did three activities at the gym tonight:
1. Treadmill run for 30 min.
2. Rowing Machine for 20 min.
3. Strength Training for 50 min.
Treadmill registers perfectly.
Rowing registers but with a Dumbbell icon as usual. (why is that? Needs to be fixed!)
Strength Training registers as "uncategorized" and does not transfer to MyFitnessPal so the calorie data there is screwed up.
I edited the Strength Training on GC Mobile and changed it to Strength. It then got the correct icon.
When I went back to the main screen I could suddenly see only 2 activities.
Strength Training had been erased!
(No it doesn't show if I log in and check the GC website either.)
This all used to work well when I bought my Fenix3 this summer but now GC is just a mess.
