Suunto Movescount updated the activity files that are synced to Strava starting the 9th of September. The device models are not being recognized by our upload parser.
As a workaround, you can export a TCX version of your activity from Movescount and upload it manually. This will properly recognize the device and barometric altimeter data.
We are working with Suunto to resolve the issue. For more detailed information, please follow this post.
This page will be updated when more information is available.
