I literally got the Speed and Cadence sensors (v 2) yesterday, attached them to my spin bike, and connected them both to Zwift last night without issue. This morning, only the Cadence sensor would connect. The little green led light is flashing. I tried to connect the sensors to the My Connect App just in case that was the problem but it doesn't see them. I tried replacing the battery. Nothing. How could this have died already? I didn't even use it yet.
Has anyone had this problem and fixed it? Or should I just return these as junk?
