I noticed that on my running activities that are part of a multisport activity I no longer see the Connect IQ datafield's fit data.
To be more precise: I do see the graphs (4th tab in GCM) but I no longer see the last section in the 2nd tab, where on other runs (that are not part of a multisport activity) I have a section for the Connect IQ datafield's FIT data.
The same is true for the connect.garmin.com website.
In the past it worked both in GCM and in the web, I was able to see the data in activities that are part of a multisport activity (I even had some bugreports about them)
If you talk to me in private I can send the link to the multisport activity.
