I posted this in the vivofit forum. Then I realised it better fits here. My excuses.
Anyhow. I have just noticed that any activity that was registered as "Fitness Equipment" (ie. gym, indoor training,...) is not taken into account in the reports / graphs of the modern Garmin Connect (it is just neglected).
Most of my training is based on gym activities, so not having them invalidates any report / graph I can get from garmin connect. At least, they should be included as "Other".
I hope this can be solved. I appreciate it. Many thanks in advance, Xavier.
