I record my cycling sessions either with a Wahoo Bolt (external) or with ictrainer (virtual cycling app), send the data (always a FIT file) to Strava and then use RunGap to send everything to GarminConnect and Suunto.
I can see all the data in GarminConnect, including the wattage of the indoor trainer (Wahoo Kickr Snap), for example, but nothing is displayed in the Suunto app. I also cannot change the data fields in the activity analysis diagram for activities that were not recorded with the Race S because there are simply no selection options. Activities recorded with Race S are looking perfect.
Since all other health data is recorded by the watch (HR, steps…), it would of course be great if the uploaded data were also evaluated, especially since they apparently exist in the FIT file. I am concerned that these units are not taken into account properly when determining CTL, ATL, Form…
