Back in October 2015, Microsoft announced the activity tracker called Band 2. Although there weren’t many problems with the device, users are now experiencing problems while syncing data through the activity tracker’s mobile app on iOS, Windows Phone, Android or Windows 10 devices.

Reportedly users can’t see the fitness data that is being synced from the Band 2 to their phone’s mobile app. Microsoft is aware of the issue and is actively working on addressing it but there is no information when the issue will be fixed, and there are no known workarounds.
