Polar all data download power number

What format is the Polar historical data? Is it JSON/XML/FIT/TCX…

If new activities are processed correctly, there might be a change/problem in the Polar archive import function.

Uploading Historical Polar Data

Any help from the mods appreciated for my problem below… Thanks! Hi. Just joined the site and trying to upload my exercise data from Polar Flow. Followed the instructions (or at least thought I did!) and got an email from Intervals to say ‘Polar data import complete’ but also that ‘0 activities created’. Any help appreciated. Thanks.
