Was doing Jon’s Mix, was 20 minutes into ride, pushing 400+ watts. Received message regarding tyre slippage detected.
Came off bike did all the checks, tyre contact with trainer, HR, Cadence and speed sensors all paired with programme. Went to go again HR and Cadence picked up, nothing for speed or watts, avatar did not move.
Changed battery in sensor, using Garmin sensors with magnets, tried the next day, the same, all sensors showing as paired, HR and Cadence picked up, nothing for speed or watts, avatar remained stationary as if waiting for me to start cycling.
Any suggestions, thoughts etc…
