Since I updated to 3.50 software on June 30 my Edge 530 no longer reports Respiration, Training Load, or Heat acclimation information. I have performed a factory reset, deleted and re-pair with my phone but still not recording. I have ridden same routes post and pre-update so don't think the non-recording is due to a mileage, elevation, etc. matter. I use a Wahoo heart rate monitor that is connected via ANT+. Tough situation to debug because all was fine during first 10 days of use and typically a factory reset for tech hardware puts matters back on track.
