Calibration prompt is enabled, but it never prompts. Manually calibrate, and get instantaneous "Success" message, with value of "ON". But actual calibration doesn't happen.
When I calibrate with Giant Ride Link App, callibration takes a few seconds, and the LED on the powermeter (both sides) blinks once when completed. Calibration with Garmin is instant, and there is NO BLINK. So calibration didn't really happen.
Before I worked this out, I would calibrate with Garmin, go for a ride, and get 60%L, 40%R. Calibrate with Ride Link, I get 50%L 50%R.
Calibration used to work before the last update to Edge530 software.
