Hey, I’ve just started on Zwift. I got a Garmin speed and cadence sensor 2 and have connected both via Bluetooth. However, when I get into either the companion app or Zwift app I get next to no speed or it just doesn’t pick up anything. Other times it will pick up the cadence but not speed.
I have disconnected and reconnected and made sure I am pairing the speed sensor and the cadence sensor appropriately.
I have the same issue and had started another thread about this (had not seen yours yet). My Garmin cadence 2 sensor pairs and works well but my speed sensor 2 pairs but does not transmit and my avatar won’t move.
Problem solved, sort of. Source of problem is IPhone 11. I paired an old android phone with sensors and works fine. Guess Garmin and Zwift don’t play nice on new iPhone.
