I ride 2 bikes with Di2 and power meter. Garmin Connect Web, and Garmin Connect Mobile Android used to show all 4 sensors status. Recently it started only showing 3. The last 2 (Di2 and PM) and 1 sensor from the other bike. It doesn't matter which bike I ride, or how long between rides on each bike, I only get 3 sensors. Can this be restored to 4 sensors please?
