Suunto app accounts are separate from Movescount.com accounts (and Movescount is scheduled for retirement). At the moment you have two options for getting data into your Suunto App account, depending on watch model:
Install the "Suunto" app on your mobile device and use that to sync your Ambit3, Spartan or 9-series watch. (Won't work for Ambit 1 or 2)
1. Create a Suunto app account if you don't have one. You might have to download and use the Suunto app on your phone to do this. (You don't have to pair your watch)
2. Login to Movescount.com (with your MC account). From the top menu, look for [user icon] > Settings > Other Sport Services. Connect with "Sports Tracker", using your Suunto app credentials.
(The history here is that Sports Tracker was acquired and turned into Suunto app)
Link your Suunto app account to sync training sessions to Attackpoint.
