Upload FIT Activity to Suunto not working

[PParnau]

Uploading a fit file into Suunto App is not working. I've tried fit files exported from MyWhoosh, Strava, garmin, Intervals.icu, TrainingPeaks.. The web returns a Success message but no activity is synced to Suunto App.

I came here to say same thing. Tried export from Polar Flow in TCX format. returned success but no update on Suunto app.
