I am using the new cadence sensor 2 and speed sensor 2 on my bike. They work fine with a Garmin 1030 but only sporadically on my iPhone XS when recording a ride on Ride With GPS (RWGPS). Sometimes the cadence shows up on the recorded ride but most times it does not. I have changed the battery on the cadence sensor and re-paired with the RWGPS app. Any suggestions for a reliable connection?
