I updated to this latest version today and it works successfully with the Fenix 3 and Vivoactive, both running current firmware, phones running Android 6.0.1. Smart notifications tested: phone calls, voicemail, Outlook email, stock Android text messages, twitter, WhatsApp. Also, both devices synced an activity. TrueUp tweaked the steps to match on F3 and GCM. The link and sync to MFP are also working for me.
The update did not retain all of the Smart Notification settings, so it was necessary to turn some on/off to return to my preferred configuration.
