Suunto Movescount updated the way activity files are synced to Strava starting the 9th of September. Activities are taking longer to sync to your Strava account from Movescount.
Suunto Movescount is aware of the issue. For more detailed information, please monitor the Movescount Twitter feed here.
This page will be updated when the issue has been resolved. You can subscribe to this post to receive a notification when activities are syncing normally.
