I've used the Speed Sensor 2 for 2 weeks now and noticed the following
1. When synced to the phone (IOS). I start pedaling and my iPhone/Garmin Connect App shows it is synced. After the workout, Garmin Connect App does not record the activity for the day. Instead, I notice it pushes to Strava first (sometimes right away sometimes an hours later) and the time of the activity is wrong. But for sure, it never show in Garmin Connect App for the same day. The next day it will show.
2. When syncing Speed Sensor 2 with my Vivoactive 3, the speed speed sometimes does not register in the middle of the workout. I have to quickly stop/stop and then it finds the speed again.
Any thoughts....
