Sometime I measure my cycling and other activities with my Vivoactive 3 but they never appear in the training status and training effect statistics. I am also using an Edge 530 and my activities from there appears as I should.
I hope this is a bug and it will be fixed soon. If it is by design then I'm very disappointed. The only reason I replaced my Samsung training watch with the Vivoactive was that I would get statitics on all activities in one place.
