Sufferfest does not see my Garmin Fenix 5
I am new to Sufferfest and am trying to pair all of my sensors. My Vector 3 pedals and Cadence Sensor connect great but Sufferfest is not seeing my HR coming from my Garmin Fenix 5. I am using a wrist sensor not a chest strap. I have set the HR to broadcast. Am I missing a step or do I need to purchase a HR strap to make this work? Thanks in advance for any assistance you can provide!
