@anthony-guillemette I believe these may be due to processor limitations but I am not sure. Since the HR is available in all screens except Navigation and Guides as the outer ring depicting zones, I do not find a graphical HR necessary.
@JackB after syncing to MC will be closed down, you will be able to use Suuntolink or the app to send your activities to the Suunto cloud. From the app you can setup connections to third party services.
