2019-05-16 With our Body Cardio product, we brought Pulse Wave Velocity to a home scale for the first time. After routine review, we now believe that this feature may require a different level of regulatory approval. In light of this, we have decided to deactivate the Pulse Wave Velocity feature on January 24. As a result, Pulse Wave Velocity readings will no longer appear on the scale screen nor will they be viewable in the Nokia Health Mate app. Your data will be retained and is downloadable.Health Mate - Total Health Tracking 4.4.0 Update
