Responding to the historical data:
I can go to my.zwift.com and download the data for any of the rides I have done
Yes, I can do that as well. However, when you bring in a .fit file into Garmin Connect and then go to the Cycling Reports section it is supposed to give you data like Normalized Power (NP), Training Stress Score (TSS), and Intensity Factor (IF). When I do this it only shows NP. It does not display or track TSS or IF. I know that in the ride report at the end of every ride in Zwift they have this data but for some reason it does not translate in their exported .fit file. Does anyone know if this is a Garmin issue or a Zwift issue.
The other problem is why the heck can't we see detailed ride data (like the one displayed at the end of every ride) on our historical data on my.zwift.com? Is this feature ever coming?
