I did calibrate my Apple Watch for the Outdoor Walk and Run (via Workout App) within first few days. Though, I got prompted to have my phone along with me when I headed for an evening walk (Outdoor). This was my first outdoor walk after updating the Watch OS yesterday. Does anyone see this behavior? Is watch loosing its previous calibration after the software update? P.S. I'm aware that the watch will loose its calibration if it was unpaired from the phone, but that is not the case here.
