I have a Fenix 5 and a Trek bike with a duotrap speed/cadence sensor. I am trying to use my watch to track indoor cycling activities using my trainer. My watch is connected to the sensor and I have input the tire size. However, when I start a new indoor cycling activity the distance and speed fields stay blank. I know that my watch is connected properly to the sensor because after i complete the activity and look at it on my phone, it shows the graph of the cadence. Any ideas of why the distance and speed aren't being displayed or recorded? THANKS!!
